Neither of those are really my thing. I raise my stats by leveling up. After that I might make a couple Vit Ups from Adamantines, but that's it.
Actually, you can devour a lot more often than you'd think-- t-rexaurs are a common encounter on the ICtH, or you can go to the training center in balamb. And I always seem to run into more malboros on the island closest to heaven than anything else xD
The only really difficult one is ruby dragons for hp+. Not only are they a rare encounter (aside from the ones in front of bahamut) but they're hard to get down to a small enough HP without killing them to be useful

Adamantines are also pretty hard, just because they take forever to find. I don't usually ever fight much around esthar, so I can't say for behemoths
