who cares they are all the same!!! i use shirrons never seen a perlick, but from all the hype ive read its all in a name i would bet you 5 case's of beer you couldnt tell the differnce between the pour on a ventmatic vs. perlick faucets.
i could only notice a slight diff between my shirron and my general faucet that came with the tower, pay attention to what your local bars use, i beleve last time i was at a bar i read on the side of the quad tower PERLICK with some genearic faucets (it was a budwiser bar/ aka brewhouse) 5 on one tower and 5 on the other at the other end of the bar.
I personelly went with shirron because they look nicer, not because they pour better or are made any better, but for straight up looks, i make decent money so i figured since i could afford it why not, if you can only afford perlicks or some genearic taps then go for it, who cares, all a tap does is delever your beer to your glass. it has no affect on the taste, color or head, so i dont see the big diff in the two major forward sealing faucet manufactures right now.
sorry to vent, ive seen this issue argued a few times on this board,perlick vs shirron... blah blah blah, go with what you can affoard and like not what some stranger on the internet reccomends!!
