I use red sea coral pro I think it's great
Sorry but it's the way you posted that I will point you out...
You think it's great or IS it great? What proof do you have of this? What other documented salts have you used compared to this?
Not trying to pick on you, just saying broad statements are...broad.
I've triedBrightwell before with nothing spectacular...*no documents

* and I've used IO with weekly water changed on a smaller tank with amazing results...
What I'm trying to say is that A LOT of reef keeping has to do with trial and error. You can use the cheapest salt, do weekly water changes and get x result, or use a super high end brand with monthly water changes and get the same exact thing...OR it's a giant mix up...It's a tough thing to decide just like lights.

What kind of corals do you want, how often do you want to do water changes, and are you dosing?
These should be your main thoughts on deciding on which salt.
I use Instant ocean, 15g water changes a week on a 50g tank with 2 preds, and LPS only corals.
What I'm trying to say is...don't post what salt you use and that's it...post what your tank is, how often you do water changes, how heavily is your tank stocked, do you dose etc...all these things matter.
