1020 all day long, active class association and plenty to choose from at the moment, will out perform the other with all the room you need for cruising. I had one for 10 years, moved on to a Young 11 for a while but i would rate the 1020 better than the Y11, not for outright speed obviously but for comfort, room and class racing.
Try and get one with a new motor, and the best sails you can, most will need an interior tidyup but normally there is nothing to scary rig or structural wise to worry about (get a survey obviously).
