I too prefer the rustic, 'old-world' good looks of natural wood handles - cocobolo, desert ironwood, lignum vitae, etc. However, for my 1-and-only hard-use/never-fail survival knife i sacrificed nostalgic 'good looks' for good 'ol fashioned, plain-Jane practicality and went with Micarta. Micarta is virtually indestructible and impervious to water - things that are important for handle material in that type of knife.
Your "Bushcraft" knife may not be the 1-and-only knife you have with you, so maybe you can opt for the more appealing look of a wood handled knife. I don't have a bushcraft-specific blade, but maybe one day i will and i'll probably opt for a wood handled version.
