Yeah it depends on what platform you're comfortable with (i.e. light or heavy). Myself I run with the PDW as my primary because I love a lighter and quicker load out. I just had a little work done to it and it outranges pretty much everything at the field that I play at (which is outdoor).
Slapped a new piston and piston head in there to replace the kinda junky stock one, new tappet plate, then got an extended tightbore barrel that runs out past the outer barrel and put a suppressor on to mask it and dropped in a stronger spring. Shoots 390 consistently and the hop up is great.
