If they're more or less equal in terms of performance, how is Sense better than TW? Genuine question.
The one major thing I can see already is that Sense does away with duplicate apps. There are solutions to match that for TouchWiz, of course, but still, kudos to HTC for doing that out of the box. And I guess the lighter Sense helps with future updates?
Is there any day-to-day software features though that Sense brings to the table that TW or no one else does?
Sense is more akin to stock android that's been jazzed up a little. Like stock android on steroids.
It does away with much of the bloat under the hood (not just duplicate apps) - for example just it's memory utilisation standing still is around 1gb less than the S7e.
It's not necessarily about extra features as fundamentally you do pretty much the same thing with both, but if like me you spent time making Touchwiz look more material both icon wise and colour wise, then sense offers that out of the box without messing with theme.
When it comes to themes not only can you create your own on the fly, but you can choose which element you want or don't want. You are not restricted to applying everything if you just want custom icons or such.
If you prefer stock android aesthetically like I do, but want the customisation that Samsung TW at least offers, then Sense offers a great combination.
Simple things like being able to swipe between dialler / contacts / favourites in dialer are small changes that do offer a nice refined experience.
Most of what makes Sense better than TW will come down to subjective preference.
