While I don't have any firsthand experience with anything besides the Brunswick brands, I can give you some help.
The Storm Crux would be a big step up, from my observations. We see tons of Storm here in Utah, so I'm fairly confident in that assessment.
The Gold Rhino Pro is best on the drier conditions. It's cover is extremely clean through the heads. If that's what you're looking for it does that very well. If, however, you want a stronger ball I really love the Mastermind Einstein for it's versatility and overall strength. A step down from that is our Brute Strength, with the Gold Rhino another step down. Hope this helps.
