How do I choose between short-sleeve and long-sleeve options for bartenders' uniforms?

For a while I just thought it was a matter of short-sleeve vs long-sleeve bartender clothes until I helped a friend set up a tiny bar of her own and discovered comfort is way more important while working the long hours at a bar. We actually spent quite a bit of time looking at different types online, including a few uniform wholesalers on Alibaba, mostly just to see the fabric types and read reviews from those who had worn them. In my own observations, the short sleeved uniforms seemed to be in a hotter-place environment, like a busy bar where the bartenders are active and working a sweat. At the same time, long-sleeving appeared to be prevalent at higher-end lounges or places attempting to create more upscale ambiance. A few bartenders suggested that long-sleeving was sometimes advantageous on cold nights or beer gardens. What really was more difficult for me to do was observe how much the material changes the climate control. It seems as if some of the thinner long sleeve uniforms are actually cooler than some of the thicker short sleeve uniforms. Has anyone who has worked beer behind a bar been exposed to both applications? Which has worked better in 8 hour shifts? I don't think I want to make a determination based on the picture in the article.
