It is okay. It's really a light weight compared to heavy load Safari and Firefox. As for flash not bad but still need works but I do like how you can block most pop ups and flashes. But still a lot of unwanted pop ups still appear I gave it a test on sites that have annoying pop ups. If only Apple and Adobe worked together to fix the annoyance of flash or it least Apple have their own flash software.
 
I use Camino on Tiger. 2.0 is a tremendous improvement in terms of javascript performance. There were some sites I used to have to open Safari to use because Camino dragged so badly, but it's quite snappy now.
