If the BOV vents to atmosphere, you're throwing away metered air that the ECU is expecting to be in the cylinders, which means running rich when you shift, as well as causing a loss of power after shifting waiting for the turbo to re-spool to re-generate the pressurized air you just threw away making a neat-o PSSSHT sound.
The only reason ever to use anything but the stock BPV is if you're running insane levels of boost that the stock valve can't handle, or if you're a ricer that wants your car to make lots of whooshing noises. So, unless you've got a massive turbo running 30 psi, or neon-underglow, stick to the stock valve. I'm running 22psi of boost on a stock WRX valve w/o issues, other people are running more.
