i have air on my daily, i like spirited driving occassionally but im not into track stuff and its fine for me.
Air handles better than standard suspension (personal opinion) but not like coilovers, its horses for courses mate if you want to track, coilys it is, if you want good all round suspension, comfortable not harsh and have the ease of moving up and down for bumps etc... and also get good stance air it is.
purely personal taste buddy
BTW air doesn't handly like a springy park toy in anyway shape or form please do not think this as its not the case. im more than happy to take anyone in my car if i ever get my ass to a meet or event and give you a little trip out.
