I've several Esees and think they are a good choice. My Becker Machax is bigger than I like to tote around, but an absolute chopping machine. Have a Habilis Bush Tool that's more knife than I like to carry backpacking, but is probably the blade I'd grab if a day of bushcraft was in the cards.
With that said, I think the best bang for the buck going would be something like a small Mora and a 12 to 18 inch machete. I've had good luck with Salvadoran machetes, but there are plenty to choose from that will set you back less than $30. They chop great, carry easy, can be used as a spatula to pull things out or the fire, rehone quickly with a file, and the first time you chop through something and hit a rock you won't cry about it. It's what I hang from my pack whenever I'm out in the woods.
