Well, there's what "works best" and then there's "what you like best" which isn't always the same thing.
Good news is there aren't any really bad choices. You'll do fine with any of the suggestions. Delrin, G10, Bone, Wood, Stag, Micarta, Acrylic. Just whatever you like the most.
If you like multiple blades, then a stockman is a fine choice. I happen to like jigged bone as a handle material over all others, but that's more for appearance and feel than anything else. For my uses, I'd never wear out a set of bone handles anyway, though I suppose they are subject to breaking if dropped the wrong way.
You can't just decide on the handle material in a vacuum, because you are dependent on what each maker offers in the patterns you are looking at. So you have to think of the knife+handle options at the same time.
If the size and blade profiles work for you, then the Buck 301 is a great knife for a work knife. I'd go with the black synthetic handles. No bone option.
If I were going out camping, then I'd take my Victorinox Farmer along for the range of tools, so that means Alox handles. Besides looking classy and having a decently textured surface for gripping, the silver stands out pretty well if you drop it in the leaves.
From the Case line, for a true working knife I might go with one of their jigged Delrin or G10 models. Smooth yellow or orange Delrin is nice too, just depends on your preferences and what is available for your choice of knife pattern.
Take a look at Rough Rider if you are on a budget. I don't have one of their stockman patterns but the two I have are good knives, especially for under $10 each. You'll have to research their handle choices, the ones I got have nicely done jigged bone.
For another bargain option, I am actually rather pleased with my (new, imported, Taylor Brands) Old Timer 93OT "Wrangler" that I got recently. It's basically a 2-blade medium stockman without the spey/pen at the opposite end. Not bad for a $15 knife. Sawcut Delrin is the only choice with that one, but it's a decent choice.
