Patch panels – What difference in quality amongst brands. Does it equal the price difference?

We are fitting out a place with new patch panels. We of course like anyone want to install once and they last for a good 20 or so years. But looking around I see a range in pricing. For example, this World of data patch panel has good reviews on Amazon

This one at Cable Monkey is 5 times as much:

OK maybe that’s because it’s right angled, however even another one they have is still a lot more

Does it really make much of a difference, especially as the Amazon one is so well reviewed? I do however want to put the best solution I can in for the customer.
Thanks in advance.
