I guess it depends where you are. Here the Signature 2026 is 750 Euro, which is about the same price as a Pixel 10 Pro.

They are quite a bit more expensive than the a-series, but I'm sure that the a series will hold up for a few more years, until GrapheneOS support percolates to mid-range Motorola phones. It's even possible, given that Pixel 10a uses the Pixel 9 CPU, that Pixel 11a will use the Pixel 10 CPU, so there might even be a new budget model next year with MTE support.
