Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
There's not much between any of the brands to be honest. Some flow slightly better, some are better at keeping water out, some are legal... just depends on what you want.
I have the VCM one and on Monday the 3 little pigs checked my car they had stopped on the side of the road looking at most cars and got a nice sticker on my car unroadworthy only because all OTR'S correct me if iam wrong use oiled filters eg K&N through searching it appears they are right no matter if its enclosed or not and you can see the filter on the VCM OTR have to source a paper one or change back to my stock for the test so in plane letter of the law for EPA and VIC ROADS cant have oiled filters must be the flavour of the month Pricks
Abit off the topic but keep in the back of ur mind
