"...you could score with anything and that all companies make good stuff"
That is your answer. I've thrown balls from most major manufacturers (and some minor manufacturers) over the years. I usually go with a majority of my balls from one, but always have some others from other companies. Previously it was Motiv. Dropping to 14 lbs this summer, I switched to Brunswick - mostly Radical. But I also kept my Jackal LE when it came in and bought a Mission Unknown.
The simple fact is, the #1 factor in ball motion is determined by the user. If you can't be consistent enough, no ball is going to perform better than others. If you can, then you look at filling your arsenal with different balls that give you different looks and balls that suit different conditions.
Despite the stereotypes out there, just about all companies offer different motions in their line up. I've thrown enough balls from most companies to know that this is true. Overall, some may gravitate towards one ball motion, but not 100%. Anyone who tells you otherwise is ignorant.
In terms of durability, I've seen people complain about cracking about multiple manufacturers. All balls can crack. Personally, I've owned dozens of balls (75+) and I've only had one ball crack. I don't wrap my balls in plastic bags or rotate them either. Most/all of my balls are stored in ball bags/totes in my bedroom.
There are balls that you will match up better with, but it won't (generally) matter what company they are from.
