Maybe if you go from one studio to another all this comes down to what is popular in your area. Genelecs are the king here, they are everywhere. So if you have them and go to another studio that has them, you do not need to worry about difference of speakers, only that each room is slightly different obviously.

As I already said, I am biased. Genelecs all the way for me (and most places in Finland).
