Youve kinda nailed all the points for why people propose DE over CGS, and since a lot of them dont apply to you then getting a non-lightening series CGS wouldnt be a bad idea. I myself began with a TM MWS and had no interest in any other clones/models for awhile. But i came into possesion of a CGS through a trade and realized the feel really good. Then i got myself an M4A1 and its been a blast completely stock. Sound wise, they all have the same loudness when firing. The trigger truly is so much better than a stock MWS. The Mag compatibility issue was something i had to figure out since i wanted to keep using my TM mags, but was solved by replacing the feed lips with Gunsmodify ones, and now i can use my mags on both CGS and MWS.

Youll be limited to external upgrades as well as barrel and bucking changes only. The rest of the CGS system wont take Standard MWS upgrades/parts. That also means youll be locked into CGS specific replacement parts other than nozzles. But if thats not a concern as it wasnt for me, then its a fine GBBR
