Same but different I guess.
I'm a 'player' ahead of anything else in the hobby, a fairly active/aggressive (i.e. like being in the mix, not that I'm wandering around jonesing for a scrap) one at that, and tend to head out at least twice a month and often more than that. I enjoy the gear side of things more than RIFs, so always keep the RIFs I have on deck to a minimum. It's been an NGRS plus one other 'primary' and the trusty TM Glock for a while and that's about as deep of the 'collection' ever goes, I just keep what I actually use. The MWS ended up getting used more because I felt I needed to justify keeping it than it was that I actively wanted to. I do always like to have a back up should whatever I want to use die on the day, and streamlining batteries and mags across the board feels like even more convenience on top of the NGRS just being the best all round option for what I'm looking for in a RIF that sees regular use.
And none of that is to downplay how good the MWS is, purely my personal preferences and experiences from juggling the two different RIFs over the last 2 years or so.
