The 3gs looks much better than the 5C, even years later. I actually hated the iphone 4 when it first came out, but I got used to it and grew to love it. I still like the 3gs because it "feels" thinner due to the curved back, although it's pretty chunky by today's standards. The iphone 4 always looked thicker, and I had to place them side by side on a table to convince myself the 4 was in reality thinner.
