The main benefit is the significantly better uptime. Johnny is meant for experimental websites and has more functionality, however it comes at the expense of stability. Tommy on the other hand is meant more for production sites...he: Has much better uptime and performanceLives on much newer hardwareHas tighter resource control; sites get suspended for load more easily to help keep that awesome uptime.Has a slightly older version of cPanel (58 vs 60)Multiple versions of PHP available (5.4, 5.5, 5.6, 7.0, and 7.1)Does not support Django.Does not support Rails. Right now, you have to donate in order to use it. When you donate, you get an invite sent to your paypal or skrill email address that lets you sign up on Tommy. At some point in the future, we will offer free signups that are limited per day, like Johnny currently is. If you donate and sign up on Tommy, you will need to delete your Johnny account since you're only allowed one account. Also, if your hosting username and forum username are the same, you will need to ask us to rename your forum account if you want to reuse your username on Tommy.
