By "we all" you mean a tiny number of hard core nerds who hang out on obscure forums. I know several people who own HTC android phones, and not one of them has re-flashed their phones or expressed any desire for removing Sense.
I've had an HTC Incredible for a couple of weeks now. The Sense UI has felt better-implemented than the Moto Droid UI, to me at least.
I've also had (and still have) an iPhone 3G/S for a couple of years. While I still think the iPhone is overall a better UI and better app store, the HTC phone is the first Droid-based phone I've owned or played with that didn't come across like an unfinished experiment in cellphone design.
I'm vaguely aware there are other options to the Sense UI, but I do not dislike it enough overall to warrant an investigation into any of the other options.
