I haven't had the best of luck with Crossover, very slow performance, very flimsy. Lots of crashes with OSX 10.9.x
I am very surprised that EA recommend this route. I would love a native client.
VMWare Fusion seems to work just fine, however the upgrade policy of VMWare is horrid, forcing users to pay for every major version bump (without offering any real tangible benefits besides new OS support).
Best regards
