I got my first Mac in 2010 (which I still use and works fine) and it came with Snow Leopard. I loved snow leopard. Then after 3 years I got Mavericks, and I was so glad to finally have new features. ( I wasn't upgrading because I was a chicken and was scared to do almost anything with my Mac back in the day.) I now have Yosemite and love the design but everything is less stable and not polished. There's tons of bugs too. in 2015 I want them to make another snow leopard. Macs are supposed to last right? With this quality control, no.
I want them to do the same thing with iOS... iOS is even worse.
Anyone else?
Having also being introduced to OS X with Snow Leopard, I was very disappointed with Lion. It seems liked a bunch of gimmicks throw in with poor performance. Mountain Lion just felt like a big Patch for Lion.
After that, I have found Mavericks to be great, aside from the Gmail issues for the first 2 months.
Yosemite is almost bug free already, at least for me. I think it's pretty solid and looks lovely as well after you get used to the new design.
So of the last 5 releases my preference would probably be:
1. Mavericks
2. Yosemite
3. Snow Leopard
4. Mountain Lion
5. Lion
(Not comparing usefulness or most powerful and efficient. Just personal impression at release.)

Yosemite has been just as stable - if not more so - than any other initial release I have used.
A.
Indeed, I think this has been the best recent testament to Apple's supposed values of quality and stability. iOS 8.0 not so much...

I hope the next OS X is a fine tuning of Yosemite (a bit like Leopard - Snow Leopard) rather than a huge make-over.
Yosemite is the first makeover since OS X 10.5 Leopard. SL, L, ML and M were all incremental adjustments since then. I would be highly surprised if OS X10.11 was anything but a fine tuning.
Mavericks perhaps is the most significant performance contribution of the Leopard series, with App Nap, Timer Coalescing and Compressed Memory.
