Similar experience for prior versions of Windows, in that they required service packs to become more stable. Couldn't comment on 8 due to avoiding the "tablet" interface it launched with (also 7 was perfectly fine....). Vista, I never understood the hate on Vista, never really had issues with it and found it perfectly usable aside from Creative Soundblaster software refusing to work, so much like any version of Windows in that regard.
10 seems less stable than 7 was, mainly due to the new version releases being buggy for me. It's why I'm now determined to defer them as long as possible.
