There's more to the comp than simple numbers...such as limb config - parallel is typically more forgiving. Cam shape - rounder is generally more forgiving. Release or fingers.... I can tell you that my 320 fps, parallel limb, 34" ata, release shot, "modern" compound, is much more forgiving than my 230 fps, 45" ata, round wheeled, finger shot, Reflex Caribou.
You really need to shoot them against each other to compare...
