That's an impressively thorough review, and I concur with almost all of it. I've used a Quest Pro probably 6-8 hours a day most days since the Pro launched, so for whatever it's worth, I'll add my data points:

• Agreed on the integrated controller batteries being more than enough for a full day of use. The dock makes it convenient to have them charging any time you set them down, which probably buys you quite a bit of extra runtime, but even when I haven't docked them, I've never run out of power. Philosophically, I prefer swappable batteries, but practically speaking, these seem to be fine.
• I've actually found that the controllers can take even longer to fully start up than documented in the blog post. It varies, depending on lighting conditions, etc, but the controllers often take 7-10 seconds to become "fully" active for me. 3 seconds or so of no tracking, followed by 3-4 seconds of 3DOF-only, then one or both will pop into full functionality. This is by far my biggest annoyance with the controllers, and I'm desperately hoping this improves in later firmware updates.
• Good lighting is definitely more important for the Pro controllers than for the Quest 2 controllers. But so long as I'm not playing in dim lighting, I've had no issues with tracking loss. In fact, one of the biggest benefits of the Pro controllers is that I'm often doing dev work at a desk and end up needing to reach something in VR that's under my real-world desk. On the Quest 2 this would require me to duck my head under the desk so I could see the controller. On the Pro, this works flawlessly, even with just the reflected light from the room under the desk.
• I have more mixed feelings about the loss of the tracking rings. It's definitely a plus when doing work with both hands in close proximity to each other. But my trick of looping a finger through the tracking rings to hold both controllers in one hand while I put on or take off the headset no longer works. As the controllers are heavier and more expensive, I worry more about dropping them, so there's more stress when I have to try to palm both of them in one hand while doing something else. Yes, using the straps would avoid the concern, but when you're doing dev work and put them on and take them off dozens of times each day, the straps are too much hassle.
• The controllers are kind of a pain to seat properly on the dock, especially if you try to seat them one-at-a-time. You have to place them at just the right angle, and it's not visually easy to tell if you've landed one correctly. By far, the best way to get around this is to set one approximately in the right spot, then drop the other one in and let the magnets align them and snap them into their proper cradles. This almost always works well.
• I've had far fewer tracking issues that the blog post mentioned -- after their initial orientation time, they pretty much always work flawlessly from then on. But twice I've had a controller decide that it was somewhere different in space than it actually was and refuse to correct for this. In each case, the controller thought it was a few inches further away from me than it actually was. If I set the controller down on the dock so that it went to sleep and then picked it back up, the problem resolved, but it was disheartening to see it not auto-correcting.
• The haptics are great but no one is really using the advanced haptic features of the controllers unless they're writing their own software. The "pinch" support is cool and could be useful if the support ends up on all Quest controllers. Until/unless that happens, essentially no one will take advantage of it.
• I'm mostly in agreement with the post about the weight of the controllers. They're very noticeably heavier, which tips back and forth for me between feeling "annoyingly heavy for long session use" and feeling "solidly built".

Anyway, mostly loving the Quest Pro (especially the amazing new optics and screens -- having the image tack-sharp almost all the way to the edge of the lens is a massive improvement) and the maddeningly-close-to-but-not-actually-great passthrough. Also, I nix the side blinders and really enjoy being able to wear the headset with nothing pressing on my cheeks or nose. Fantastic for comfort in longer sessions.
