FWIW, I felt the same way about my Pixel 5, and was equally apprehensive about jumping to the Pixel 6 Pro based on the reports of issues by some users in this forum. But based on my own positive experiences with the Pixel 2XL and the Pixel 5 -- which I attribute largely to the fact that I am a very light user who does not use a non-stock launcher, or load up the device with lots of apps, or play video games or watch videos on my phone -- and more recent testimonials of users here who have not encountered any problems with the Pixel 6 Pro, I decided to take the plunge about a week ago when Best Buy dropped the price by $200. And after a few days, I opted to stay in by wiping my beloved Pixel 5 and setting it up for my even more beloved wife.
So far, the Pixel 6 Pro is performing just as flawlessly as my Pixel 5, and I'm getting similar battery life -- two days on a full charge. In fact, to me it just seems like an XL version of the Pixel 5. If anything, it's my impression that the display and the sound (for music, at least) on the P6P are noticeably better. The only issue I've had is adjusting to the larger size. Specifically, I've always preferred to use the ultraslim leather sleeve-type cases from SENA, which protect the device in my pocket but make it easy to extract. But I quickly found that this type of case won't work with the Pixel 6 Pro, because the camera bump on the back protrudes so far out that it routinely catches on the lip of the sleeve when inserting the phone. So I've changed to a wallet-type case, which probably provides greater protection but takes up more room in my pocket and requires a split-second more to open when I want to use the phone. Other than that minor inconvenience -- and an occasional lapse of the Always On Display that now seems to have been remedied by the May update -- I'm a very satisfied Pixel 6 Pro user.
Of course, every individual has to exercise their own judgment based on the available information. I'm not trying to persuade you to make the same decision I did. But in fairness, it ought to be acknowledged here that some of us have found the Pixel 6 Pro to be a reliable, smoothly functioning phone.
