Atmel (now under Microchip). They have great documentation and software libraries. And they actually acknowledge hardware errata in the documentation.

More so for Microchip than Atmel --- it's pretty common to find on some of their newer and more complex parts a ton of errata, among which there are some extremely "WTF!?" ones like "feature X does not work at all".

Yeah I love those. They highlight features xyz on first page of datasheet. Then on the last few pages its like btw features xyz dont work on rev A-F. And your supplier doesnt know what revs they have...

I used a SAMD21 for my latest project and I was definitely impressed with it versus STM32s.

I will say that STM has definitely released better tools that make it much easier to get designs up and running (STM32Cube specifically).
