they've been changed at some point the standard units are made by KYB. They can be a bit pricey through Subaru but you can get replacements from Camskills at a decent price without having to go down the coilover route.
Not sure what BCCs are like, hopefully someone will be along to say. Like any suspension set up it depends what kit you go for - street, track, etc. things just get stiffer and crashier if you can put up with it
