Another one to look at is Fairweather. They are made by Nitto like Simworks, VO, etc, but have some different designs.

I think these Nitto track stems are pretty cool. https://www.benscycle.com/nitto-ct-8...80_870/product

Generally speaking, I like threadless stems. IMO it is a far superior design mechanically. That counts for something with me. While many are ugly, some can be attractive. I'm very happy with my Nitto UI-21EX, which makes no apologies for its threadless-ness. Only took a little getting used to. Now I like how it looks. My gestalt shifts a little easier than most people my age I suspect.

Let's not forget the Rene Herse original type. One of the prettiest stems ever.
