In the last four years or so I've owned lyriks, boxxers, totems, 36s, 40s, 66s, 888s, 55s to name but a few. Some I've owned multiples of/ Most came on complete bikes, some were upgrades.
IMO setup makes all the difference, a well setup rs fork will feel infinitely better than a poorly setup fox. Obviously. I think the fact that Fox do so appeal to "all the gear" bling merchants is partly to blame for their bad rep – the people riding them have no clue about set up or maintenance. Fox dont make bad forks, just fragile ones that appeal to tarts.
Overall I think the rockshox I've owned have been the superior forks in most instances. Granted my 40s were stiffer than boxxers but they pissed oil everywhere on a regular basis and were no better damped. Rockshox are on a roll at the minute imo with some great products – I feel like sampling some BOS goodness in the near future though. Should be interesting to see if they are any better than the usual suspects.
