For bling I like K-edge. For cheap I like SRAM. Avoid Racewear 3D printed (unless it’s all your aero bars will fit 🙁 ), they really aren’t worth it!
K-edge place the Garmin at a mid-stem level, SRAM is above bar height. I prefer the lower option, personally.
EDIT: just opened that racewear link from DR. Buy that! It’s what they are worth. I paid full retail for a brightly coloured one and the bolt rusted and the plastic stained. I also have a red one under the saddle of the track bike that I feel was a rip off (but is the only option!)
