I'm still in the mode where I wouldn't buy a bike I can't try on first. If you have to order the bike blind, then realize that the smaller size will have less stack height, They didn't give the detailed geometry on their site that I could find with a casual look, but on Geometry Geeks, they show a 2021 Priority 600 as having a 3.8 cm difference between the larger two sizes of frame. So that means, assuming a equal amount of spacers under the stem, your bars will be 3.8cm or about 1½ inches lower on the smaller frame, Yet your saddle height will still be the same.

However the smaller frame is also going to be the more maneuverable handling bike when riding with a group of people or on twisty roads. While the larger might feel more like a luxury sedan when on the open road with no sharp turns.
