Putting the "meh" UI esthetic aside, I didn't want to upgrade because my iPhone 4 had become a pig under 6, and 7 performs a hair worse than 6 in terms of speed and battery life.
There are, however, some valid reasons to upgrade in spite of iOS 7's drawbacks (don't get me started on how the new lock screen keypad makes it harder for me to unlock my phone with just my thumb).
* Call blocking has "finally" (gruber's favorite line lately) been implemented properly -- if you are one of those people who are increasingly getting more telemarketer calls on your cell number, this is a huge deal.
* Safari runs faster on iOS7 than iOS6. 90% of what I do is browsing, so this can be a tradeoff that is well worth making.
