Studio One has three levels: Prime (Free version), Artist (has some limitations) and Professional (Full-featured flagship version).
Within the Artist version are a bunch of VERY useful and useable plugins natively. It is FAR from "pointless". However, you can purchase the booster pack for Artist, which, among other things, gives you the VST support. You can customise Studio One to you needs if you don't need the Project Page with add-ons.
