LVT owns them all.
As for aircraft, I'd vote for the Curtiss Commando. It's basically a goon on steroids

Twice the troops, more power. By the way, that is 50 troops, the goon took 28.

Another option would be the Messerchmitt Giant

130 troops, or 12 tonne payload, oh, and 17 defensive guns. But it's sloooooow.
Or even the Horsa Glider.

Now this can be towed by various aircraft, down to even the goon, but was fequently towed by bombers. Carries about 3.5 tonnes, which would be 25 troops, and I also heard they carried GP's in them. The Gigant of course, also carried vehicles.
A good angle on the Horsa in AH would being towed with a heavy bomber that also has some payload

It would land on very small patches due to its special flaps.
