I started with Sonar 8XL or whatever it was called, I don't even remember now. Upgraded to X1 Expanded, which was amazing, then got X2a, which was absolutely terrible and now I have Platinum.
Platinum is amazing. Kinda reminds me of X1, but even better. Works awesome on Windows 10, love the streamlined workflow....fantastic. I'm putting this here for anyone who is on the fence with upgrading to Platinum. I'd say... do it.
