I used to love HTC phones but over the years even what some call better build quality doesn't sway me back. I started with a Sprint version of the HTC Hero for a work phone. From there went to the Evo 4G and then the Evo 4G 3D but after that the version of Sense UI on the 3D really kind of turned me off to HTC. From the 3D changed over to the Sprint version of the Galaxy S2 and carried that until the S3 was released. Touchwiz was a good change for me from Sense and to be honest the lighter plastic build of the S2 and S3 appealed to me as I was carrying two phones at the time with a personal phone as well.
During that time I was carrying a iPhone 3G and a 4 for a personal phone so when it came time for me to give up the work phone, my contract was up on my personal phone so I went S3 over the iPhone 5 and have since just upgraded that to the Note 3 and currently getting spoiled by it's huge display (which feels really small now). Touchwiz is definitely getting heavier compared to the S2 or S3 but even with that, plus the plastic build of the device most people despise, isn't enough to have me looking at HTC again. LG, Moto, Nexus devices, and even the current and next iPhone have my eye in regards to my next device.
