The 11 series has a new MediaTek modem compared to previous Pixels(since 7 I think?). The old modem had power efficiency issues during poor cellular signal as well as a relatively lengthy GPS lock acquisition.

I don't think there is enough evidence yet about either but I can attest that GPS feels improved over my 7. It's only been 1 week though.

The non-Pro 11 has a much larger photo sensor and has more base storage. Everyone has different priorities. I'm not saying which is better but trying to give a more complete picture.
