BGM:

Obviously my favorite is FS One, and yours is G4. That said here's
what I think.

My thinking is why spend time flying any sim unless the physics are
top notch. Doing anything less is a waste of time. Also on top of
that it's "negative training".

The FS One videos are out there to let people make their own
decisions. I know I have posted this before on RCU, but here's some
comparisons between real spins and FS One (various planes in the sim
and then real video of the same planes):

Real: http://www.inertiasoft.com/videos/fs1_RealSpins.wmv

Spins are the biggest challenge for any sim. Find videos of the other
sims that look as real. I've not found any and this includes going
outside R/C simulators and into commerical sims and research.

The numbers game is one thing, but it's worth making a side-by-side
comparison of planes. In FS One we don't count permutations as
separate airplanes. Also, we don't have some gimmicks like blimps and
hawks, etc. We include airplanes that are very popular - a lot from
Hangar 9 and E-flite that are on the market today. We do have a
scaling wizard that will scale an airplane up or down in size and the
physics is scaled automatically. So with that there are an literally
an infinite number of airplanes in FS One. We included many scaled
variants already setup. Here's the list that we did not include in
any numbers count on the box labelling.

Aside from my opinion on all this (and I do think our physics are top
notch and nothing is better), here's another opinion:
