Overall, my 6 has been super smooth, seamless & without a glitch since I picked it up the Saturday after launch date. I'm glad I didn't load the 8.0.1 update, for whatever reason, especially after learning of all the havoc it caused so many. I had a few apps crashing and whatnot, but that's pretty much a history item since 8.0.2 was dropped.
Sorry the OP regrets leaving the wonderful world of Android. My advice is to run, don't walk to wherever you bought the iPhone, and pick out another Android. There have no doubt been 10-15 new Android phones released since you left for iOS...so you'll have a great selection to choose from.
