Every person I've known who has taken classes has either really enjoyed their teacher, absolutely loved their teacher, or will fight till the death till you agreed that the teacher they had was the best. At level 1 the curriculum is the same as every other section at the training center, really what makes the difference for me, is how the class grows as it progresses. But if you're looking for a straight up answer, go see a lot of shows with the teachers who are offering sections, and see for yourself. I agree with Hal here when saying you'll learn better from someone you think is great than not.
either way you'll learn and have a blast! Good luck!
