Fenix PD35 feels way way better than sofirn anytime.
I own a sofirn SP31 (not the 2.0) as an alternative to the pricy PD35 but it’s no comparison in “feel”
Yes the sofirn has better brightness but Fenix overall feels superb.
Tactical forward clicky is stiff and solid without feeling difficult to depress compared to sofirn mushy button and mushy switch.
There is no air gap in Fenix light and the tailcap rubber feels grippy even when covered in wall paint powder dust or any contamination.
Sofirn gets mushy inside and it takes about 1mm of travel for the rubber boot to touch the switch. Air gap yo. At least Convoy S2+ feels better than fenix (but they’re reverse clicky)
The side button on fenix clicks well and feels define with less to no wobble. I still prefer Fenix old rectangle rubber side switches but both old rubber and the new tac button are good.
The sofirn old silver button and the new black button both had wobbles and needs to depress quite deep to engage the modes. It just feel inconsistent.
While this may be a grey matter of opinion, I always liked the defined circle hotspot on the old fenix PD35. The new tac all had hotspots fade to spill.
Sofirn beam is nice. No complains to that.
Fenix always looks good to me with their fade to ON light output compared to many flashlight which goes 0-100 when you depress the switch. It just feels professional. Even their small LD12 lights has them and I still love my LD12
But overall sofirn is definitely great value when comparing light output to expensive fenix. Use it a while and you forget all the nitpicking I said in my opinions about their button feel. It’s like comparing mushy membrane keyboard to cherry mx mechanical switch. Just a preference thing. Thanks for listening to my opinions. 
Oh and I like how Sofirn can be disassembled in the future (at least in my unit)
Fenix just glue everything
