I'd say in terms of pure performance iOS 8 has been more clunky. I do remember iOS 7 initially being delivered with slower animations, but they were still at 60 fps, which I don't find to be the case in iOS 8 in several instances.
The point is though that these would be considered details which the average iPhone user wouldn't really notice. Then again, I'd argue that this is the place to be if you're not the typical average user.
It should be noted that bugs are a different matter, where both have been riddles with issues.
Well Arstechica and Anandtech would be a few. But I find it very surprising, given the amount of articles even on Macrumors, that it would somehow surpass people that iOS 8 has been shambolic. I'm not really talking about bugs, since both releases have been riddled with various different bugs. I'm referring to performance really, where I feel iOS 7 generally had a very smooth and consistent experience, which cannot really be said to the same degree regarding iOS 8. The iPhone 6 and 6 Plus struggle in some cases which to me is really just a sign of how unpolished it's been.
What I do find strange is how it seemed to have hit a nerve on you. You take this awfully personally as if I somehow said something derogatory towards you personally. Cool your jets. Is it really necessary to become that upset about it?
I honestly think one would have to be fairly oblivious to somehow not see that iOS 8 has been awfully shoddy. Here's a pretty good summary of what some people within the community or industry feel. There are a few noteworthy people there. Marco Arment had a pretty interesting post about the state of iOS 8, which gained a lot of traction.
Remember, both have had their fair share of bugs, but I'm mostly talking about performance and the so called 60 fps experience.
