If you felt too upright you might prefer the next up frame size. Check the geo charts for both bikes.
Any full suspension bike will feel squishy compared to a hardtail. You'll need to dial in the shock for your weight before you can know if it will be too squishy for you in the open mode. The great thing about the Genius 910 is you get a middle mode for the rear shock that takes the travel from 150mm down to 115mm by closing off an air chamber. I've used that setting for the entire ride on mellower trails.
