I have been a loyal Google user, I have a Nexus 7 2012 and a Nexus 4.
I would like to say that both are going strong but and nexus 7 suffers a from the abysmal performance that kicked in after the first couple of years. Timing seems to fit how Google wants to retire products which is a shame, we would all like newer toys buy most of us cannot afford the upgrade cycle.
The nexus 4 suffered from the poor battery life but a replacement from eBay solved that. Dropping it and breaking the screen twice in quick succession was the end though.
That said the nexus devices in their prime were excellent and the pricing was competitive for the quality and brand.
Now the pixel devices, oh come on Google get real, price sensibly and own the market.
