Maybe I'm just lucky, but even this argument is quite ... meh

In practice, Apple has shipped updates longer than competitors, but there is no guarantee. With Android vendors, there's a guaranteed support life.
It's a question of the degree you trust that part performance predicts future performance versus written policies.
Samsung claim a support timeframe but they never released a page like Google's one (https://support.google.com/pixelphone/answer/4457705?hl=en) as far as I know
And even if we use Samsung claims as some sort of guarantee, we also need to take into account that while Google use the "at least" terminology, Samsung uses "at most" or "up to". Which basically means that they commit to nothing since a "up to 4 years of updates" (with one major update per year) could both means 1 or 0 updates or 4 updates
