I liked Profesora Benedict! She's enthusiastic and happy to help and the classes were always fun- there's a lot of group work emphasized and she puts on music whenever you're doing an in-class exercise. Material-wise, 2020 is definitely a lot harder than 2010 since it's so subjunctive heavy but like most of the intro courses, it's very hard to do badly in the class since the grading takes a lot of different components into account.
