OP here. This will likely be my final update. (if something unexpected happens that pertains to this thread, I'll probably comment again.)
The grooved and plain versions each have their pros and cons. The grooved one is a little more interesting, it has a better grip to it, and the anodization is done better (in my opinion), but of course, some people think it looks like a phallus. The plain one has a classic simplicity and won't be mistaken for a phallus, but it's more slippery in the hand, and the anodization is kind of dull and shows fingerprints *very* easily. (FYI: Lots of times people think that anodization is wearing off, when in reality, it's obscured by fingerprints. Wipe your knife down with an alcohol wipe, and the anodization will usually pop back up.)
Just over 100 people voted, and it's close, but the "plain" people are slightly ahead of the "grooved" people, so I started seriously considering the plain knife. I really do wish the anodization was better. Regardless of what it looks like in the photo, it's a little dull in person. But I have a complete ano setup (120V power supply, Multi-Etch solution, and rock tumbler), so if I wanted to, I could theoretically redo it, though I'm still an anodizing newbie and am learning as I go.
Unexpectedly, a solution that is better than I could have hoped for presented itself yesterday. I purchased a Ferrum Forge Archbishop (the slight step up from the Fortis 2.0, which is what I have) in blue with carbon fiber inlay for a rather good price. It looks really good and has none of the problems of the two knives I have asked you to vote on, while retaining just about all of their good points. So, once the Archbishop arrives, I will wind up selling both of these Fortis knives.
Thank you to everyone who bothered to vote in the poll.
