They are faster, a bit sturdier, can be upgraded to feed ALOT faster, look nicer in my opinion, although they hold less.
(Talking about the Halo here.)
maybe it might be worth from now on to put comparison at the start of each thread
that way when people need to look for any kind of comparison thread it will come up with a list of them
now on to you question
the halo force feeds the paintballs into the breach of your gun by keeping a stack of balls under contant tension and as such is able to feed at a much higher rate
with a standard board about 17-19
reloaders about 22
and a v35 halo up to and about 30
the egg is not a force feeder just a modified agitator which when balls fall into the fell it pushes toward the tube to your breach and as such will only just about feed 15bps max
