Looking for upgrade advice

We currently have a 2014 Peplink Balance 30. Even though we don’t use it for WAN balancing, we are committed to staying within the product family. I am trying to figure out what benefits I would get to upgrade to the Balance 30 Pro. Faster? Better how (not looking for WAN balancing benefits)? More efficient? Or do I just stay with the current Balance 30? About 25 users. I use it for VPN/FireWall to a AT&T Fiber 50mb internet feed.
