Same question as I was asking in 1978. The answer is all plug in breaker panels are roughly the same and haven't improved hardly any since that time. If anything they are less sturdy and well constructed now than they were then.
For the most part the breakers seem to work ok when you put them in, although due to the way we wire due to the codes , it comes nowhere near to pushing the upper limits of any of it, so it is actually kind of hard to really make judgement calls on who makes "the best". Seems like now the best question to be asking is - which brand of afci breakers has the least issues? and then go with panels made around that.
