This falls in the "for what it's worth" category, but when I had my Combat Fighter Experience" at Fullerton Airport a few months back, they had Extra 300's with both Hartzel metal props and MT composite props. I asked about their preference, and they said they preferred the metal props by far. The MT props were much more maintenance intensive and for them, the performance benefits weren't worth it. These planes are running hard all day long, so they are placing a much higher demand on them than I imagine we would and I'm sure it's possible that the decreased maintenance interval is something we wouldn't notice.

One value of the more expensive prop, of course, is perceived value. One car is perceived more valuable than another sometimes just because it cost more, not necessarily because it is better. If you gain performance with the 14.4K prop, I doubt it will be 8K worth (all IMHO). For that price you could get two Hartzels and have a 4-blade. J I personally have an aversion to composite props, but that’s all I say. My dad was with an organization in Mali with a Caravan with composite props and they didn’t last worth anything with the sand. That was a long time ago, but the memory sticks. So, I would recommend going with the aluminum cheap prop, but that’s just me. The composite looks cool, but at 2,700rpm and 200mph, you’ll hardly notice. Oh yeah, and with the aluminum prop you don’t have to do all the pinhole filling and sanding. That’s enough of a reason in itself. J
