I'd just do a comparison on construction, features and price. But one thing I can give a recommendation on is to buy the largest size you can fit in your space. It's amazing how fast they fill up...
I’m not sure where you are, but I own a Browning safe and would buy another before other brands. I deal a lot with the product manager for Browning and the local Browning rep. Great product in my opinion.
I have a liberty. Looked at the brownings and liked them a lot. Small town liberty dealer is what I chose to support. My one gripe is I have some old very long Gustaf Mausers and they screw up my usable shelf space. The center wall in mine is to short to support the middle of the biggest shelf due to those rifle lengths. so I have to be careful with weight load on that shelf. I also have the liberty ammo can. It was cheap and I like having all of my ammo locked up.
I've done a bunch of research and I'm getting ready to purchase a rhino ironworks USA gun safe. Does anyone have any opinions or experience with higher end guns safes?
