Galaxy S III feels much cheaper and looks cheesy. The one thing I liked about the HTC was the unibody case which Anandtech praised in their review for feeling great in your hands.
I always ignore the spec junkies on these forums since I flash all my phones with custom ROMs to remove all bloat.
I was using a first gen dual core phone from early 2011 until last month with Cyanogen Mod and it was as smooth as butter.
I agreed.
When I handled the GS3 in store. It feels plasticky all over.
I would get the GS3 just because of the better brand name and hence better resale value but since the OneX is $80 cheaper, that would negate the resale value.
