Why people hate Touchwiz so much?

[EarlyMon]

I've used a couple of non-Samsung phones, and that red-underline under words it thinks are misspelled annoyed me. It was like nearly every word, except a few simple ones like "in", "on" or "and". Couldn't see any way to turn it off.

On an HTC, settings, language and keyboard, toggle button at the top.

I am stock(used to be rooted) I do however use a home launcher. I switch between Nove and ADW. The only reason is I HATE having a 4x4 grid. I don't understand why they can't make it standard 5x5. :/
