Best smartphone in all category's would be the iPhone. Worst would probably be any of the Droids with low memory... The free models.
Basic phones are all about the same quality today. Hard to say. I see very few issues with those anymore.
Agree on the smartphones.
Have had no issues with the Gusto2, Internsity2 and Convoy2. We have come a long way since that stupid Motorola charging port on the E815/T720 and the breakable Razr antenna. They all have names now, which is cool as well.
agreed on the samsung smartphones the VZW lineup is nothing to write home about. From feature phones I used to really like LG's products but as of late about the only device I actually appreciate is the HotShot from Pantech which has surprised my thus far.
