ok some guys are using catch can others not the ones not using it say that they use no oil or see residue on tail pipe like with the ccv or have to add oil so why the need for the can.??

I guess it's all personal preference, the catch can definitely won't hurt anything, mine has been running as is without one and I surely don't have black tail pipes like I did before the delete. I'm going to keep mine absolutely the same just to be a Guinea pig and see what and when will fail first. So far everything is working as intended.

And as far as the $100 vs $15 catch can goes, the Mishimoto one is very well engineered with internal baffles that are very good at separating oil from air vapors. They are a very popular upgrade with the BMW N54 crowd.
