My gut reaction is follow the great teacher, as in the end, the teacher is what really matters.
But - - - a bit of sober second thought, and I was reminded that we actually did this scenario for a daycare/ pre-school. And unfortunately, the great teacher was far too busy dealing with the massive administrative burden of her start-up to really do any teaching. Totally understandable - but the kids had a rather mediocre year, a far cry from the outstanding experience our friends had had with this teacher in her old environment.
