Is there that much difference in quality of seat cover brands like PUI, Distinctive, and Legendary? Are there any I should avoid? In the past, I have installed seat covers with good results, but I am not sure what brand they were.

 

My experiences with Legendary and PUI products have been equally positive in terms of quality - both accurate and excellent. Wait time for order fulfillment may be the biggest variable you'll encounter between these 2 brands, price differentials not otherwise withstanding depending on any sales either may be running at such time of your purchase interests.
