I've used both of them. When I first started it was Lisa. And I really liked her course. Then I stopped for awhile  and eventually got back into it and saw that there was a newer beginner course with Anders so I thought I'd try that as well. I've since "graduated" to Rock level 1 now and I'm glad I took part in both beginner courses as I'm sure both teaching styles benefitted me. I didn't dislike anything about either course.
