The GOS x Motorola phone is likely to be high end, like the Pixels. I expect possibly something along Moto’s “Signature” line (gsmarena review / mirror).
And yes, Motorola does make pretty good phones. As do other China-based OEMs (Xiaomi & BBK) and Taiwan-based OEMs (Acer & Asus). Comparatively, Pixels are almost always overpriced for the spec; though, I exclusively recommend Pixels to anyone who can afford it, regardless of whether they’d flash GrapheneOS/CalyxOS.
Moto’s midrange “Edge” series do have overheating issues, though they do tend to pack a pretty decent battery unit. With fast charging (especially 90w & 120w) on offer on decent midrange Androids, I don’t particularly worry about “battery life” anymore.
I would recommend their “Edge” series for the “vanilla” Android feel (though, they have been guilty of overindulging in too many mods of late), the (shatter-resistant) POLED screens, the “thinness” of some of their “Edge” variants, & the quad-curved screen (though, some who aren’t used to these may come to hate it).
