The main difference is the limb shape. The recurve has curved limb tips, on the hybrid, the entire limb is one big curve. The limb pad angles are usually different, whether one piece or two piece bows, such that the hybrids usually have a bit more pre-load or early load on the limbs. That may or may not cause them to feel to draw differently.
Also, on a recurve, the limb tips open toward full draw. That has the effect of keeping the limb tips from being pulled closer together as full draw is reached. On a straight(er) limbed bow, the limb tips are pulled closer together as full draw is reached. This makes the string angle more acute and causes more felt finger pinch. The shorter the bow, the more prominent this phenomenon becomes.
