Personally I prefer HTML only. Flash often has long loading times. I would prefer to disable Flash in my browser, mainly to stop Flash-banners, but I couldn't because it stopped me from using so many sites. Also, at school, Flash isn't installed, so I can't use any sites that uses Flash-navigation or something.Of course Flash does have it's positive sides to, it looks the same no matter what browser you use and you can make som cool sites, but I don't think that makes up for it.
