So, let me get this straight: You HAVE seen bugs on iOS 8, which others HAVEN'T seen, and you HAVEN'T seen bugs on Lollipop which others HAVE seen? So, for you (and only for you), Lollipop is more stable. That's what you need to take from this "experiment"
Imagine the people that are seeing the bugs on Lollipop - they are just the opposite of you right now, wondering what is going on ATM with Google.
It’s Official—iOS 8 Is Apple’s Buggiest Release to Date
About a month and a half into iOS 8: We’ve had four updates (8.0.1, 8.0.2. 8.1, and 8.1.1), and we’re officially at 23 listed bug fixes through iOS 8.1. But with iOS 8.1.1, which just went live Monday, Apple doesn’t site specific bug fixes, but rather a general “This release includes bug fixes, increased stability and performance improvements for iPad 2 and iPhone 4s.” It’s not a leap to assume that “bug fixes,” plural, refers to at least two to three fixes, and that stability updates to older iOS devices could bring that number to at least five. That officially makes iOS 8, thus far, the buggiest iOS yet.
