I'm looking for the most upright position hence why I'm paying attention to the Stack.
Thanks!
Yes; that is why comparing different bikes, the stack tells you the front end frame height.
Ideally you want to find a frame with enough stack so you don't have to run a bunch of spacers e.g. 30mm below the stem.
Stack and reach is the best place to start. From there you get into other things like bb drop, chainstay, trail, seat tube angle etc.
