The first beta release of El Capitan has so far been the most unstable version of OS X I've ever seen. Far worse on my system (2009 MacBook Pro) than Yosemite. It locks up hard just about once a day, and I have no idea what is locking it up. Graphics corruption in various places, mostly seen in Safari, embedded videos and such. I really wouldn't recommend any early beta versions of OS X to anyone that only has one machine available or anyone that doesn't have multiple full backups to restore from. That's my 2 cents so far. Hopefully all my crashing is helping Apple find some of the bugs.
