I have always used skyfire with no issues on my Aria. But on my atrix it only allows me to go to mobile only sites for alot of sites and it wont allow video playback either it gets stuck on buffering and never completes. I just tried it on my aria and it works just fine.
Now before people start saying change my user client, that was the first thing I did when I downloaded Skyfire.
