The H3 wins hands-down in all of those categories. I'll get into why in a bit.
Some things to consider...
The GX and H3 are trucks. The MDX and RX are FWD crossovers, and the FX is a RWD crossover. GX is a rebadged 4Runner, while the H3 is based on the Chevy Colorado. MDX is Accord-based. RX is Camry-based. The FX is derived from the same platform as the M45, though I wouldn't call it "M-based" despite the two being closely related mechanically. So you've got 3 different categories of vehicle going on there, which may help you narrow your choices.
The FX is definitely the most performance-oriented onroad. The H3 is more capable offroad or in adverse road conditions.
The AWD systems are also a lot different. The MDX is always in AWD mode, but has a snow mode that improves snow performance. The RX is either full-time AWD or FWD only. And the FX is either full-time AWD or RWD only. Of the 3 cars, the FX has the superior AWD system, acting like RWD most of the time but giving the front tires power when needed.
The H3 has 4WD (with a 2-speed transfer case). And the GX has a similar system but 4WD is enabled full-time (you still get 4lo, though).
Since the H3 and GX are trucks, they'll offer the best durability and towing capacity. But the cars will offer better ride quality, handling and fuel economy.
H3 either has a 3.7 liter Vortec I5, which is good mechanically but not as refined as the excellent I6 it was derived from. It also feels gutless in such a heavy truck. If the H3 you're looking at is an Alpha, it'll have a 5.3 liter Vortec V8, which makes the H3 a much more appealing prospect.
I'm also not fond of the 1MZ and 3MZ (3.0 and 3.3) V6s found in first and second gen RXs. The engine is low on power, unrefined, and just not up to par. The 2GR (3.5) in 2nd and third gens is an excellent engine, however.
MDX gets Honda's 3.5 and 3.7 V6s, which are good but, being Honda powerplants, lack torque vs the VQ and 2GR.
And the GX get's the 2UZ V8, which is not bad, but short on torque for its size (though still far torquier than any of the non-V8 options in the list).
And the FX gets a VQ35, unless you man up and get an FX45 (hint, hint) which is the best engine in the lineup, short of the Vortec 5.3.
So it comes down to whether you're looking for a truck, a crossover, or a sporty wagon (the FX sitting alone in the latter category).
