Z2's RR2.0 course is a much better learning environment than the MSF's parking lot drills. It's geared more towards real world riding, and not full-on track riding. By the end of the day, they will have you out on a racing line, and you'll get to see what riding a track day can be like.
MSF's Experienced Rider Course is a good refresher of the basics, after you've been riding for a while, or you're looking for a nice insurance discount.
For the money spent, the track time, and overall learning experience, take the RR2.0 course.
