I used to use Virtual Box, but moved to VMWare 3 years ago.
VirtualBox was having the same issues as VMWare is currently having.
Plus VirtualBox requires much more manual setting up than VMWare as follows:
1. You have to manually apply the new version of addon's every time Virtual gets a version update.

2. If you want to share files with the host, you'll need to manually change user permissions to allow write privileges for your Linux user. (off the top of my head I can't remember which user account you'll need to change permissions)

I don't know if VirtualBox has improved since then, but be warned, you may be jumping out of the frying pan into the fire.
