either way the answer will be the same, her is another example an easy one that all us old timers will have seen first hand many times. ( and im not even that much of an old timer only 6 years here)
A TM M4 bone stock 280fps on a .20 pitted against an older JG M4 bone stock shooting 390fps on a .20 (theese are ral numbers of those guns in stock form)
the TM will hands down have better range and accuracy, the TM will have better tolerences have a better hop up unit and rubber and likely a better barrel too.
upgrade the TM to 390 fps and it will have the same range and accuracy, but yo can use a heavier bb and gain some range and accuracy like that
