There are a lot of good airframes in this size. I would take a serious look at the ExtremeFlight 64" MXS, many also love the 60" Extra, and I've flown both the 3dhs 58" Edge and EF 60" Edge. Those are nice for 3d planes. But you mentioned tracking, so the Extra or MXS would be more of my pick in the EF lineup.
I've flown a 58" Extra MX. I just don't care at all for PA's construction technique's, I put the MX together for a local buddy. He has owned it for over a year now and has barely ever flown it. Had serious motor and ESC issues, required sending both back to PA eventually for replacement, which took over 6 months to get done. But even once the plane is flying right he doesn't really enjoy it much. The PA planes tend to be super floaty and light. Which gets them blown around by wind and hampers their precision flying abilities. Should help low and slow 3d, but when I flew it I didn't like the way it flew there either. I really can't remember all that many specifics of why I didn't like it (was over a year ago) only that it was certainly not a plane I would want to own.
I would take a 59" Slick or 64" MXS all day long over it. The MXS has become my absolute favorite plane in this size. (It's really a 60" plane when you pull the wing tips off)
