You are going to get a lot of different answers to this question, but here is my take.....Set Up!

Setting the plane up for hovering and 3d will make that particular plane better at hovering. One key setup point with hovering is thrust line, not only right to left thrust but up and down as well. If you have to hold excess rudder in the hover you have side thrust issues, if you are holding elevator you have up/down thrust issues. Spend time setting this up right!

Next is CG, throw and expo. A plane with a reward cg will be easier to keep in a hover....most if the time! Use the CG, throw and expo to get a good balance of control in forward flight and hovering. There will be a small sacrifice to either side of this set up, but a happy medium is not impossible.....it just takes time.

After all this is done the last factor is confidence and which plane can build that confidence quickly! For this I would recommend something with a thick fun fly wing ( not funtana ) and the lowest wing load possible. Any .40 fun fly plane 4-5lbs with a Satio .72, thick wing, and semi long tail is a good choice. If you are thinking .60 size go with a 6-7.5 lb with a Satio 1.00.

FYI, I own a funtana 40....it is not a 3d trainer, I use it to sharpen my skills for my bigger GS gassers.
