I have only used the irons on my NM and Socom for years but decided to scope up as an option. I looked at all the mounts available, talked to people who have used the various ones, and read everything I could on the internet about them.
I had no budget, just wanted the best and something that could be detached easily because I prefer to practice with irons.
I ended up with the Bassett mount for both of them and could not be happier. Until you mount one it's hard to "get" how it works, but once you mount one the light bulb goes off and you realize what a clever design it is without all of that weight and quickly detachable.
Very, very pleased that I made the right decision for me.
