I only have LPVOs. I prefer the FFP in them, but it isn't a deal breaker, I can live wiht the SFP reticle. Some match shooters never change magnification so, SFP is fine for them. In a tactical situation, you'll want to lower to the magnification to create a wider FOV. With SFP, you have to dial back before engaging. With FFP you can engage at any magnification.
So it depends on how you use it.
Depends.
Take the LPVO in SFP or FFP using well designed reticles thick enough for these types of scopes, even moreso with daylight bright illume.
If these are used close up to mid range on 1x or on low power in a PBR scenario then hitting an object of mid size is easily done and done with speed while enjoying the wide FOV. Makes no difference if SFP or FFP here in this space as described because they are affectively at or so near their zero that it doesn't matter.
Basically few are shooting long range on 1x but there are a fair amount of airgunners shooting longer distances on higher mag using these scopes. Here most will be using the highest mag in the SFP scope because that is where mil or moa values are correct. If not then they usually are at mid mag in the above mentioned PBR scenario because they want a tad more magnification and they've chosen to sacrifce a little FOV. It's at the farther distances as far as using holds that are the problem if not on max mag. However one can skip holds and dial the solution.
With FFP, again especially with daylight bright illume, you can use any holds in the reticle on any magnification and at any distance so pick which one that suits the best right then and have at it. I admit that most of the time I'm either at 1x or 10x with my main LPVO even though it's a March DFP shorty but I can choose which magnification without a thought of holds ever being incorrect.
Man 1x doesn't work for me for general shooting because 1x looks like 9/10ths x. However this scope is mounted on my AR and lives on 1x most of the time for CQB if ever needed, or for 3 gun. But when shooting offhand on steel at a precision pace I'll have it at mid mag somewhere. The sensation is way better than using 1x here and more confidence inspiring too.
That's the nice thing about my March, it's crazy versatile. Let's say it's on my air rifle and I picked 3x for a little more magnification and I wanted to shoot at 10Y so I just hold up x amount, then the next shot is PBR so I hold center, then the 3rd shot was 200Y so I just hold up x amount. It still has a decently large FOV, has just enough magnification to make out a small-ish target, I can see the reticle plainly, and engage accurately using holds.
On the AR I shoot at our 1143Y steel but it's on 10x and I've dialed which is what I'd do if I had a SFP 1-10. 10x helps some.
It's a DFP scope so it's the best of both, SFP, FFP, and has daylight bright illume and glad to have it since whatever engagement is needed I'm GTG.
I didn't mean this to be a March advertisement but writing this made me ponder it's attributes.
If I had to choose a FFP or SFP LPVO I'd choose a FFP as long as the reticle was done like it should be. In other words it needs to be seen on 1x but not intrusive on high mag.
In lower magnification ranges (3-12x / 3-9x) there are twice as many SFP.
