Between the two, the M4/CF is definitely worth more on the secondary market so I would EDC that one. Also, the peel-ply CF hides grime and wear better than the gray G10. The CRU-WEAR would probably hold up better in storage with a light layer of oil and a fresh dessicant pack. I have been rotating between both: M4 at work (dirty environment) and CRU-WEAR casually outside of work.
