lol only Ultimate's online/Guild quests are easier than Tri's, I'd say. The Village quests for low-rank are essentially the same, and Tri's were most certainly able to be done solo.

G-Rank is, of course, harder. Not only because of G-Rank specific sub-species, but because of a boost in health and damage for every other monster. As for the final battles rivaling a single powered up Alatreon and two Deviljho, yeah, I'd say they're harder.

You'll just have to wait for the G-Rank Alatreon quest to accurately compare ;)
