I was mostly using Nexus (LG Nexus 5, LG Nexus 5X, Huawei Nexus 6P) and Pixel (3a, 4a, 4a 5G, 6 and 7) phones until “Pixel 7”.
I had good experience until “Pixel 4a 5G” but started facing issues (overheating, poor cellular reception, fingerprint sensor not working properly etc.) with “Pixel 6” and “Pixel 7”, possibly due to the early generations of Google Tensor with Samsung Exynos modems on Pixel 6 and 7.
From “Pixel 7”, I switched to Samsung Galaxy S23 and later recently switched to Samsung Galaxy S25, primary for the Qualcomm Snapdragon SoC. I did not face any issues with the S23 but I wanted the dual eSIM option in S25.
All Nexus, Pixel and Samsung phones (expect Pixel 4a) mentioned above are/were USA Factory Unlocked models. Pixel 4a alone is non-USA model, though still factory unlocked.
I have been debating buying either Pixel 8a or 9a (not USA, same country as the Pixel 4a) to replace the Pixel 4a (that is still in use) for my parents. While I like the Vanilla Android experience on Pixels, I am hesitant to buy the Pixel 8a / 9a because of the Samsung Exynos modem.
@twodogs I suggest getting the S25 Base Model over Pixel 9. IMHO Snapdragon SoC / Modem is much better than Tensor SoC / Exynos Modem.
