School me, Differential covers

Going to out on new differential covers when doing my rear gear.

Was going to do PS front and rear but that about AEV too. I can see its only for the rear, my front is a dana 30. I have an AEV lift maybe leaning PS/AEV combo. 

But the AEV is twice the price. I don't rock crawl, so no need for the strongest one. I run PS bumpers as well, so one reason why I though of those.

Is it really more about brand I prefer, looks? I know some have dipsticks, so more protections, etc.

Both PS and AEV seem highly rated.
