that would depend entirely on what you want.
do you want a dmr that's based off something realistic looking/feeling, or will anything that lobs bb's with dmr energy?
do you want silence, do you want noise, do you care about "recoil" (insofar as recoil applies to anything airsoft), what's your expected round count, budget, tolerance for precision, teching skills etc etc.
however given it seems this thread is primarily a conversation peice then the WE svd, because it's cool.
