Welcome.
Comfort is good at speed, quite flat so there's less push forwards - increases wrist ache / core fatigue at lower speeds this is because it raises seat height so additionally those vertically challenged struggle to reach the ground.
Comfort seat is plusher but I didn't get on with it as I spend too long at low speeds in town. I think it net reduces braking fatigue thanks to the shape. All in should be good for long distance touring out-of-town, but may induce wrist ache anyway if you're weak in the core.
Sargent Seat - more sporty - similarly flatter towards the front/tank. Little lower and less spongy than comfort, but still more so than OEM. I can feel it across the back of the thigh as you roll off the edge of it and I sometimes become aware of that, and it's a little uncomfortable when I do. Nice materials though they don't grip and so decelerating requires a firmer grip of the tank with the knees. Wide back section help you centre yourself and gives support on acceleration. Decent half-way-house from OEM to Comfort.
