I'll repeat what I think is some really good advice I got when in your position and asking the same question;
Buy the one you like. You'll most likely fly it better because you'll fly it more and that is the key, practice. If you get into IMAC and gain some more experience, then one particular airframe might suit you better for your preferences but at this stage of the game it isn't going to matter much.
Also, please be aware that the same model type from different manufacturers may not fly the same so it's not just a case of which airframe but can include which manufacturer of a particular airframe....
