Hey guys, listen to this. According to MUNK, you too can go out, spend $2000 on a Mark 23, and you will know what you're doing!
I'm sorry, I've seen more posers with their high end Gucci guns (including many Mark 23's) that couldn't hit paper at 15 yards. I also have to repeatedly tell these same people to stop pointing their guns at me and others down the line. Intimidating, no. Scary... oh, very scary! Just remember, money can't buy you knowledge or experience. ONLY, hard work and training will. But I digress. The question was about the gun, not the shooter.
As for which one is more intimidating? I would agree with Apeach. It's almost shocking the first time you look at the muzzle and realize how big that .50AE hole is. It's similar in feeling to looking at the muzzle of a shotgun. And don't get me wrong. I like the Mark 23 and if I could comfortably get my hand around one I'd probably have one in my safe.
BTW, my friend has a DE .50AE (polished nickle too) and it has never burped a failure. He's capable of offhand one shot kills on boar at 50yrds and party ballons at 100yrds. He also keeps it very clean and that seems to be the key to keeping the DE running well.
