Vinny Maurowrote a review of FOX Racing Shox 34 Float 27.5 150 3Pos-Adj FIT4 Boost Fork - 2017 on June 16, 2016
Familiarity: I've put it through the wringer
It was no secret that the Pike swiftly knocked Fox out of the top spot for 140-160mm travel forks. The Pike came out and was lighter, stiffer, smoother, and had better dampening. It seems to me like it took Fox some serious R&D to mount a comeback, but based on the 30 or so rides I have on this fork I'd say they have pulled it off finally.
The 34 chassis makes for a super light fork, but they've got it plenty stiff. In a blind test there's no way I could tell you which is stiffer this or a Pike. Whatever they've changed with the air spring has definitely made the beginning stroke much more supple as well. My 2015 (maybe 2014? had the RC2 damper) 36 Float was very rough and chattery and made for numb hands on long descents, this are is greatly improved on this fork. The RC2 damper in that 36 I had was pretty decent as well, but it was unfortunate they used the CTD damper in the 34 chassis exclusive since the CTD gave you very little control over compression dampening. This Fit4 damper has the same useful on the fly adjust-ability of CTD, but with much more actual control over the dampening.
Overall this fork is light, smooth, and easy to set up (with some basic understanding of the fundamentals of suspension tuning, not as turn-key as the previous CTD). I still dig the Pike for sure, but it's nice that there is now a comparable offering from Fox to choose from based on exactly what you need. If weight is a priority then this fork is a no-brainer over the Pike. Other than that, I'd say you really can't go wrong either way. Got to love when some healthy competition in the market makes for such sweet products!
