> The only vendor I actually enjoy working with to any degree is ST, and only design boards using their uC's for that reason.
ST has good documentation most of the time, but for a while some of their higher end MCUs had a lot of weird bugs and errata that were simply not documented. I haven’t used any of their modern parts recently but I’ve heard the situation has started improving. I have some friends who were ready to abandon ST altogether after losing so much time on a design to undocumented bugs and parts not behaving as documented.
