I think the handles on the Dozier are too flexible, and mine even has a bit of blade wobble. They aren't bad knives, I just find them over-rated and over-recommended.
So between those two, I'd take the Buck, especially if I could check it in person first.
But I'd prefer the AG Russell Featherlite over either of those due to the known quality, steel choices, and mechanism design. It does cost a bit more though.
I might even prefer the Gerber Gator with 154-CM steel. I'm a big fan of the round 'grippy' handles.
For an all-purpose outdoor knife, have you considered a fixed blade?
