The Meta Quest Pro has the best processor on the market installed: the Qualcomm Snapdragon XR2+. This one is a step up from the Snapdragon XR2 used on the Quest 2 and Pico 4. The XR2+ is said to provide up to 50% greater sustained power alongside a 30% boost in thermal management. A good processor ensures that the headset and application will run smoothly without long loading times (the CPU is not the only factor determining loading times).
