Nexus phones were cheap compared to iPhone, that was their whole differentiation. For example, Nexus 5 launched at $349 while at the same time iPhone 5 launched at $649. There's nothing comparable in those prices.

If you really did buy all of these, then you certainly didn't pay the same price. And after that, there was 3 years break before first Pixel - so you used a bricked phone for 3 years? Or it worked fine for 3 years?
