Is anyone using a rugged/heavy duty case?

Otterbox Defender for my XL. I always buy Defenders. I removed the terrible built in screen protector and replaced with the Yootech tempered glass screen protector. Perfect combo of protection and screen clarity once I removed the built in screen protector.
I just hate how dirty the silicone gets.
 
I have the Seidio Surface case with kickstand. I also have the holster. I have used Seidio for the last 4 phones, and they are great.

It's a two later case btw. It's got a TPU layer on the inside and a hard outer shell.
 
Supcase Unicorn Beetle with the belt holster. Also have a tempered glass screen protector installed. This case is the closest to the otterbox defender without all the extra bulk. I do also have the defender and I switch back and forth from time to time. I do believe the defender offers more protection from drops.
