It sucks.
I really love that gun, too. It has similar design to my favorite M1 garand.
But, I pride myself of being "OFF META" so I've had to remove it from my load outs.
I haven't even tried the Mac 10.
Think about it. The DMR (and Type 63) hits harder than the Oden while having less recoil and a faster fire rate.
It hits harder than some snipers.
The Mac-10 is OP but not game breaking so, imo. You still have a chance with an MP5, MP7, Fennec, AK74u, etc. and some of the shotguns.
The Akimbo Diamattis is WAY worse. There's nothing you can do close range against those.
