as @flanders noted I’ve heard it’s essentially the same part/mfg just marketed as two different labels. I have no proof to back this up just that I’ve seen/heard this several times through the years...
I don't think anyone can confirm they are the same part. I assume there is some difference, but...then again, a lot of aftermarket parts come from one mystery supplier.
Hard to know. But it doesn't seem like too many failures from either brand.
