Ball motion? In my opinion, no. When I was on Track staff, Track had stuff that shaped much differently than AMF or Columbia did (back before Ebo bought the Columbia family in 2007).
Today, I still think this is true because I see differences in motion from Radical stuff compared to Brunswick even though Brunswick pours Radical. Same goes for Lane 1 and Global as I see differences but Global pours Lane 1.
However, as for durability and overall performance, I would say they are quite similar. I saw similar issues across all the Columbia families in regards to covers, pour issues, etc, all of which would affect overall performance. The same casting machines are used, same finishing machines, same individuals on the lines, etc.
Further, Phil from Radical and others will state they can add stuff and use different resins than the company that pours for them...so just because they come out of the same factory does not mean they are similar in composition.
Hope this helps,
