6.1 is better with wifi from my experience, and it's also faster and more stable than 6.0 was for me. The threaded sms is somewhat annoying since I can't back up my messages, but battery life hasn't been a problem for me really. it may have changed some, but when the battery life is possibly 2 days, a few hours is a significant percentage of that time compared to the average charge cycle on a normal cell phone.
