I could be reading something wrong here, but if folks are comparing the VFC ('Umarex') and TM 416s I'd say that's a real apples vs oranges. The VFC is much more your standard AEG inside with somewhat higher quality externals by comparison, but realistically you're not going to ever get it to have the bolt lock/release, moving bolt and recoil simulation that the TM has out of the box.
I do wish TM did make slightly beefier and more realistic outsides with the stock muzzle energy VFC tends to provide, no doubt there and I'm sure lots of people feel the same, but equally the energy put out by the TM is plenty good enough given their hop units and having owned a few NGRS guns for some years now I've grown to really love the empty mag feature.
