Well, we all have our preferences. I'm taking caution updating my 6S+. Since I know iOS 13 on 6S+ will be most likely laggy, judging from what happened to the 4S if you decide to update past iOS 5.
But it will be different since the CPU and GPU performance is getting exponentially better with every year. Todays iPhones will last even longer than an iPhone 4s.

I upgraded from iOS7.1.2 to 9.1 yesterday on my iPad 2. I felt forced into to doing this, as Pages/Numbers/Keynote on the Mac is incompatible with Pages/Numbers/Keynote available for iOS7.1.2, and I use all three extensively.

Pros:
• Safari renders much faster.
• Safari crashes much less. And when it does, it just reloads the tab instead of crashing the application.
• Some games run better. Alto's Adventure runs noticeably smoother, ie. more FPS, and with less random loading spikes. Quite surprised by this.

Cons:
• App launch and quit is significantly slower. Both the time itself, but animations also lag quite significantly more. This is the worst thing about the upgrade IMO.
• Safari is much heavier. Takes MUCH longer to launch and be ready, animations lags more. Opening tabs is slower. Selecting the location bar takes more than a second for you to see a response. If you spend most of your time in Safari, don't upgrade from iOS7.
• Most things are marked slower, such as switching between applications, going through Preferences, etc. Curiously, it does happen on and off, as sometimes things responds as fast as I would hope for, and other times there's a clear lag.

Am I satisfied? Well, I would never have updated if Pages/Numbers/Keynote was compatible, let me put it like this. It is not much worse than 7.1.2, but the overall speed bumb here and there makes it clear that there's a difference. Still useable of course, but it is clearly showing its age. I hope 9.2 brings optimizations, you know, the ones Apple promised when they announed iOS9.
Pity you didn't update while 8.4.1 was being signed.It delivers almost all of iOS 9 at much higher speed and responsiveness

That's just wishful thinking, but I agree and hope that will be the case for years to come. As for current supported old iPhones, there are indisputable video evidence on YouTube showing how much slower and laggier an iPhone 4S feels running iOS 9 in contrast to iOS 5.

In the future, I'd love to see the performance differences of an iPhone 6S running iOS 9 compared with an iPhone 6S running iOS 13. If history is any indication, iOS 13 will make the 6S feel like a laggy piece of crap.

Hopefully less so.

Consider, at the time of release the 4S was a very powerful smart phone. But it still paled when compared with desktops and laptops released then.

The 6S is also a very powerful smart phone. But it does compared with many desktops and laptops.

I think that's what the poster meant by the advances in mobile tech.

Can't say for sure if the 6s will be super slow in 4 years, as I'm sure iOS will advance as well, but I would wager that the 6s is better poised for longevity than the 4s was.

And to be fair, the 4s is perfectly useable on iOS 9. It slow, sure, but not too different from how it performed on iOS 8. In fact I found it had smoother animations especially in the app switcher and home screen. If all you're really using your phone for is phone calls and texts, the 4s on iOS 9 is fine.

Myself, I likely won't have a 6s in four years so I'm not too bothered by whether it runs iOS 13 or not.

I'm just enjoying it right now and it's a fantastic phone.

To add: at the cost of more overall issues in general with iOS and a horrendous safari experience. But at least the ui was smooth while it crashed.
Safari issue can be solved by using Dolphin,Chrome,Firefox.The overall stability of iOS 8 is not as bad as you make it sound.Definitely not as severe as iOS 9 lag problem

Just as there are some workarounds to some iOS 9 stutters here and there really. And for many who have had stability and functional issues with iOS 8, I would say those are certainly more severe than some slight visual UI issues.

Even with animation and transparency off, the iPad2 my workplace bestowed to me is pretty sluggish compared to newer IOS devices. It's not great but you can use it in a pinch. I basically use it for light safari work and a few other non-demanding tasks.

IOS 5 and 6 were the only ones that didn't slow down my iPad 2. 7 onwards was disappointing.

lol, Some make iOS 8 sound like it was a complete unstable mess.

No to me it's a workaround/downgrade because I like safari and have my stuff synced through iCloud.
You can use different browsers and sync through through them as well.Besides all these browsers use Safari's engine so they are all the Same

I understand what you are saying, except as you say, why should I have to workaround something? I have chrome installed and I find it better on some things, I like all my desktop stuff synched; so I'm not against workarounds, but on the other hand, it's do as I say not as I do?

Because using Chrome does not result in any feature compromise and your crashing problem is solved.On the other hand,turning down visual settings is a compromise as you are getting a worse experience than you were getting on 8.4.1

Well not using safari to me is a feature compromise and turning off visual settings is a must. We can disagree on this, no harm no foul.:)

That makes no sense.When you turn down animations you are compromising visuals.Chrome has ALL of the features of Safari and in addition it also supports desktop sync.What features of Safari does Chrome compromise?Both are browsers.Both use the same engine.Apart from the interface they are nearly the same thing

The UI is different for each one, the browser sync is different and requires using a different browser on the desktop as well, Chrome doesn't have access to the faster JavaScript engine that Safari uses, Chrome doesn't support content blockers, etc. You will honestly say that turning down animations that don't affect functionality or anything really aside from subjective aesthetics is a compromise, while using another browser that actually has functional differences isn't? Is someone's leg being pulled here?
