I mean there are hard walls and soft walls that may be the “preference” you are thinking of? But that is dependent on the bow not the archers (2 archers with the same compound couldn’t have a hard and soft wall). Draw length is adjustable (with in a range) on compounds but is based off your anchor.

Tension releases have a mechanism to “feel” the change in back tension as you squeeze your shoulders together when anchored. (Think of holding a pen skinny ways in between your shoulder blades). That motion creates tension which rotates your hand slightly and that is what causes the release to fire. Otherwise it would release as the archer was drawing due to the physics behind a compound making the heaviest part the initial pull.
