Can't be answered without knowing the model and maker.
Personally, I would get the Well MB01 L96 because it has better performance. It gets 500+ fps while the DE M50 gets about 315 - 325 fps. For a Sniper, you want a good fps to get better accuracy.

M41 is not a standard airsoft model, did you mean a different one. Also it depends who makes them.
