I agree that Whiterun's house is extremely simplistic, however for as much as I actually use my house, I don't need the extra perks. the enchantment table would be nice though. The biggest reason that I picked Whiterun though is that there is a Smelter right next door, which are hard to find in Skyrim, there are 2 blacksmiths in whiterun, The companions are based in Whiterun (my main guild) and Whiterun is just a nice town all together, much nicer than Riften.
