It does not really explain pros and cons but it explains how they work and what the diff is.

The bigest difference is that a FFP  with mil dot or other balistic reticle marks in the FFP can be used for holdover at any power where the second focal plane reticle appears the same all the time so it can only be used for hold over at the highest power.  The other thing is with a scope with second focal plane reticle where the back eye piece turns to adjust it, loosen the locking ring a little and while looking through the scope wiggle it a little - it will leave you wondering if there is any chance it will ever hold its zero.   FFP is a good thing.

The biggest drawback of some FFP reticles is that, as magnification decreases or increases and the reticle gets smaller or larger, it can be either hard to see or too blocky...all depends on the design. I wouldn't mind having an FFP but for my application - occasional shots at game animals past my max. PBR of 320 yards I'm going to go to 10X anyway on my SFP mil-dot reticle (which is its ranging power). FFP really shines when you have multiple targets to engage at different ranges, i.e. tactical shooting.

ffp biggest advantage is when you get have a spotter, they call for moa/mil correction and its the same correction for any power, if your a lone shooter it depends on your ability, how good you are with the set up etc. 2 other advantages also with an ffp are shooting at movers which is similar to holdoff corrections with wind, which changes with the mag, on a sfp and point of impact changes with different mag. due to wind.
sfp scopes  as an example may or may not be set up for hold up or range estimation on the highest power. ex. some nf, ior, and all zeiss rapid Z aren't used on their  highest power,
rear occular wiggle is usually worse in fast focus euro type  which a steeper thread pitch than ring tightened models, but in either case its immaterial as the occular only corrects the image
