desirable marking?

I'm getting ready to start my next HK416 build. I'm planning to use an MR556A4 upper, and I already picked up the HKP enhanced trigger guard.

I'm currently trying to decide between going with M27 markings or G38 markings on the lower.

For those of you who are into HK clones/collectible builds, which marking do you think is more desirable in the US?

One of my goals with this build is not only to have an accurate-looking 416, but also to retain as much value as possible in the future.

Would you personally go with M27 or G38, and why?

I'm especially interested in opinions from people who collect HKs or have experience with clone/remarked builds.

you choose for me.
