Mixing brands doesn’t necessarily show up immediately in a finished product. It may not show up on a client for months or years, but experts agree that eventually there will be problems.

Yes, it’s great to use this or that top coat, it’s your favorite, but it belongs on it’s matched gel polish. I had a tech bring in a ‘universal’ gel top coat. She said she read the product info. I read it again and yes, it is ‘universal’,but only within the product line. That part was overlooked.
I know that it’s expensive to have a few different gel lines, however, you will be assured of proper application, cure and wear if you do as the brand asks.
