Samsung Rant- My first phone ever. I hated it. It broke slightly after a year of owning it with the internal display cracking or something like that.
LG Rumor Touch- I got this phone as a replacement to the Rant months after it broke, and for a non-smartphone, it wasn't that bad. Although that phone is what go me to hate slide out keyboards.
HTC Evo 4G- Upgraded to the Evo about two years ago, and loved it at first. But with the Gingerbread update, then the 2.3.5 update, I started experiencing some problems, mainly big problems with Sense.
Samsung Galaxy SII Epic 4G Touch- Upgraded to this from my Evo about a week ago and I will not go back to HTC. Great battery life, very lightweight, and Touchwiz is better than Sense by a longshot in my opinion. Although I was disappointed it came with Sprint ID at first, I soon realized that Sprint ID brings the phone back to the stock Gingerbread launcher(with the Sprint ID logo taking the place of the browser icon, of course).
