Might be Google's but they certainly aren't Android flagship phones. Samsung, Huawei, and previously Xiaomi are packing better hardware with innovative technology like under-screen fingerprint scanners and multi-lense cameras.
You don't seem to understand the word "flagship". It doesn't mean the most bodacious ship in the fleet. It means the one from which the admiral flies their flag. This is clearly Google and the Pixel, in the Android analogy.
