I can only guess why your experience was so different from most people's. Still, I was a windows user up until around 2010, and it was an objectively terrible experience for me on the whole. While there WERE flash and Silverlight websites that weren't terrible (in fact, I seem to remember a few that were great, was Strong Bad flash?), the majority of things people think of when they think "flash" is stuff that would show up on newgrounds.com or a random video stuffed into a flash container. So, I think both can be true, but most users' primary exposure to flash was low-quality software created as people's first game or similar. If I were to diagnose the issue retroactively, it would be that adobe flash had way too many foot guns (around memory management, I'd guess) for non-professional software engineers, which also happened to be the most significant users of flash on the WWW at least on the sites I frequented.
