Having played and worked at a paintball field for over 6 years, I've learned that getting into a battle of PB vs Airsoft is never worthwhile -- its like religion or politics. But I'm stubborn and love a good debate.
Yes, Paintball is much more popular. Theres no denying that, its one of the most played "Extreme Sports" in North America and Europe. In the past few years Speedball has become huge, and is on TV now; while its all flashy markers and colours, its still good for the sport.
Now for that video that you posted Flexor, you'll have to note the following:
A) Rarely does a woodsball team play in Yellow. Its called Camo, and most of the time REFEREES wear yellow.
B) That was shot in the same way most TV shows do it, putting speedball teams in the woods courses and let them shoot thousands of rounds at each other to get the right "footage".
Fortunately for most of us, thats not how paintball is played.
The footage of airsoft is more of how Woodsball is played. Whether its straight elimination or objective based, you sneak around in the woods and work as a squad to complete your tasks.
And the gear?
OK so most of paintball's newer stuff is in flashy colours. But thats not to say that "real" stuff doesn't exist.
The Zeus and WG-series are made by
Armotech, a company that makes both Replica and Speedball-type markers. I own one of those pistols, but I also own a bright blue Autococker (jokes all around, folks).
Airsoft is certainly not a "booming" business in Nova Scotia. There are no public fields, let alone much of a community for it. But all of the PB fields have said that no Airsoft markers are allowed, period. Its a shame, I'd love to try Airsoft; but paintball is still my first love and probably will stay that way.
The Customization battle is something I won't argue about because I don't know enough about Airsoft to be able to properly talk about it; but I know that almost every little piece of my Autococker can be replaced to make it function better and more efficiantly. That goes for just about every marker on the market.
Cheating is something that is going to happen no matter what. I see it every day I ref, and theres only one way to deal with it, Ejection. Airsoft probably has less of a cheater base than paintball does due to its close-knit circles, but thats not to say that there isn't a huge player base of honest paintballers.
Major events, well Paintball has at least 5 D-Day games all over the States that draw in 3000+ players every time so I don't know how that competes with Airsoft events. I know that our field pulls in around 250+ for scenario games, and the numbers are steadily rising.
I should keep going but I have work to do.
Edit: Changed just a few things about the armotech section.
