from what Ive read Bobo is at 13w vs Kiwi at 15w, and Kiwi is not making noise whilst retaining a form factor I can fit in the official case when not in use. Im willing to give it a punt. If it extends battery life by even an hour that's probably all I need. Either way I have no bias so will put up an honest review, if a better option appears later I don't mind upgrading.
I was actually playing with my son earlier, we played multiplayer games from full charge to empty, and my 3 year old Quest 2 was roughly draining at about the same speed as my Quest 3, so the battery life is I guess not as bad as I thought on Q3, although I think my Q2 is not as good as it used to be.
Don't forget the quest 3 uses a more powerful cpu and higher resolution, it will drain at a faster rate, but I think it might be a larger battery over the quest 2 to balance it out
