At the end of the day, a SFP scope is perfectly fine and a fair bit cheaper if you are either shooting at known ranges or can range (using a rangefinder) your target and do the necessary arithmetic for holdovers or work at the optimal magnification for the compensations of a BDC reticle. If, on the other hand, you are using the scope for ranging and/or shooting at unknown distances, FFP is your preferred choice.
As to selection, I somewhat spoiled myself by getting used to Zeiss Conquest RapidZ SFP reticles on my hunting rifles (they have great glass and take a licking and keep on ticking) and using a laser rangefinder so, given my advanced age (67), functional age of 1 knee (81) and 1 ankle (93), I'm very happy to avoid courses that require running or extensive hiking. Also, most of my target work is at fixed ranges, so for me all but one of my scopes are SFPs. I'm currently wrestling with choice between a Zeiss Conquest with Rapid Z1000 reticle (SFP) (about $800) as I shoot mostly .308 Win for targets using 175gr Sierra Match Kings for one of my precision rifles or a NightForce NXS (about $1,900) or Vortex PST (about $700 w/ SFP, $900 with FFP) or Razor (about $1,900 IIRC).
The most important determinant is what you will really use the rifle for.
I have 2 scopes, for example, for my .375 H&H hunting rifle, both mounted in Leupy QR rings to fit my QR bases. My 3-9x40 is useful when I'm using 260gr bullets for elk or moose (although I've seen only one moose and that in Rocky Mountain NP so he was quite safe)which at 2,700 fps nearly match the ballistics of a .30-06 shooting a 180gr bullet out to 275 yards or so and I put a 1.5-6x24 on when I'm anticipating big game (like a bear) up reasonably close and using 300gr bullets (if I'm going fishing in Alaska). I have a Zeiss 3.5-10x44 with a RapidZ800 reticle on my 7mm RM...I know where it will put things out to 800 yards at 9x using 160gr bullets. Since I have yet to take a hunting shot longer that 325 yards, I'm covered. Targets, not so much...
