Like any other weapons, it is subjective. I like my 938 for summer and "dress up " carry. Little heavy but I like the fact I can carry hammer back. For edc I carry my g19 for capacity. Both serve me well.
I agree about the shouldering. However I use the buffer against my cheek. With the 10.5 barrel I also have plenty of foregrip to hold on to. Not much difference between that and shouldering.
As for carrying yes the charger is great when broken down. But if you don't have the takedown the ar when taken down doesn't take up that much more room.
If you read my prior post , I had a charger takedown. I liked the platform until I got it. At 60yrds I was drilling hole in hole but it just felt impractical.
