I’m slowly getting back into playing, but I’m also a somewhat serious woodworker. Just my thoughts but I like what I’ve seen in the “roasted” variety. I’ll look into it but idk about the roasting process, in woodworking burning or charring wood was traditionally done to make the wood more resistant to moisture and insects. Today it is almost entirely aesthetic. There is a technique called ammoniatization where chemical gasses are used to tint wood, it’s very attractive especially with oak. Given it’s a quality brand and the neck itself is structurally sound I think it’s an aesthetic choice. Usually fretboards are lacquered or otherwise sealed/coated. I’d say playing both and getting the one that speaks to you and feels best is the way to go
