Already saw those videos. The guy is horribly biased. I've used Android and still prefer iOS over it.
There comes a point when customization is just for the sake of it. This guy likes to repeat how "customizable" Android is, but I think he misses the point of what an OS should be: a platform for apps. Honestly, if I was given too many options to customize, I would go crazy over how I would want the phone to look. I'm perfectly happy with iOS's appearance.
That's my big problem with Android: I'm definitely what you'd call a "power user", so installing custom ROMs and the like isn't a big deal for me. So that's what I did on my galaxy nexus.
That said, it takes so much time to find a good ROM, then they don't have all the tweaks you want, so you either need to patch it in yourself (and support it as the system updates) or look for another ROM.
All in all, you could spend your entire life searching through all the slightly tweaked android variants.
Once you've actually found one though, there's not a whole lot to do on the device. The google play store is still a list of "meh"s. The constant wave of fresh and exciting apps that you get on iOS just doesn't exist on Android. Yes, you can sideload apps, but outside of ridiculously easy piracy I haven't seen a case where that's essential. Maybe that's why the store is so barren.
That's why I'm still with my iPad and my next phone will be an iPhone. You don't spend all your time tweaking how the device should work; you spend your time using it.
