"Depends who you ask.Stay with Rockshox."
I dunno, Rockshox haven't exactly had a clean slate for past problems?
Heavy stantion/bushing and stantion wear isn't difficult to achieve if you don't keep up with dropping the lowers
2 step on Lyriks (And mission control? or not?) was hasn't had the best track record?
Motion Control units can leak under harder use
I've also found lower rebound adjusters are prone to rusting/seizing up within 3 months, A dust seal blew mid ride on me not so long ago, with a loss of air pressure (though the lowers aren't supposed to hold air?), ball bearing U-turn adjusters can jam/seize
That said I don't think I'll ever pay the extra for fox over heavily discounted Rockshox I've bought previously, the little bit of extra weight (And the 07/08 ATA issues) of marzocchi has put me off too, that and no 20mm axle on 44's (one of the mags reckoned QR15mm 44's were flexier than fox 32 QR15mm too)
That said (again) my 2004ish Marzocchi MX Pro ETA 120's have been faultless, yet to open them up. Only issue I have is being 30mm stantions, QR and a touch weedy looking I think they might be a bit flexier than newer (32mm) rockshox I've had
Also, a failry pointless sidenote, certain Rockshox spares are ridiculously pricey. over £200 for older revelation uppers (Though I fox are that money too). A travel spacer I think is something like £15. Fox(or rather mojo) I think wanted £1 when I looked
