Canon vs Aftermarket Battery Grips

I recently acquired a 6d2 with a canon branded battery grip. Previously I had only had an off brand grip for my t2i. I’m looking at getting one for my 90D and trying to decided which one. To my hand the canon one is so much better feeling than the off brand one I have. Are there any off brands that meet or exceed the canon quality or should I just spend the extra to get the brand name one?
