Pride used to be so much better. They didn't allow guys to lay and pray. After a little bit of inactivity on the ground, they would stand them up.
The UFC allows guys to hold guys down for way too long imo. I get it, i'm not a jiu-jitsu purest.....but many times i'm not seeing jiu-jitsu either. It's guys stalling, doing the bare minimum to make it look like they are trying to improve their position while throwing a weak punch that would hurt a guy off the streets. Chael Sonnen, Jon Fitch, Jake Shields, etc made careers out of it. Shields was a good grappler but his standup was as bad as they come.....so he wanted nothing to do with exchanging. Even a guy like Maia learned to throw as he got more experience.
