This is not a claim but more of an observation i myself am interested in, but i wonder which 'secure element implementation' is/will be the more 'robust' one, if any. The titan m2, or the one on the SOC of the Snapdragon 8 Elite Gen (5/6?). Atleast from a harware perspective the implementation seems different so i wondered if that could translate in a potentional difference in 'robustness', for lack of a better term in my english vocabulary?
Actually, perhaps this concept could be approached even broader, i imagine a lot of hardware might be different, so perhaps that could translate itself in the Motorola being 'better' than the pixel on some aspects and vice versa. It is probably possible/likely the radios for example could be 'better' on the Motorola either from a hardware- and/or software perspective etc.
So my current opinion with my lacking knowledge on this matter is that it probably is likely that the Pixel will be 'better' on some specific aspects, and the Motorola perhaps on some other aspects, but not one is better than the other in full, atleast not for the first phone that is born out of this collaboration. If this first collaboration seems fruitful, i imagine the Motorola might well surpass the Pixel over generations as GrapheneOS gains more input on hardware components.
