I wouldn't worry too much about what other riders say, I'd pay attention to how you *feel* on the bike.
A good fitter will look at how your body works, where you are and aren't flexible, where you are strong, and how you naturally tend to hold yourself. (Even which way your ribcage moves most when you inhale! A narrow aero grip would be useless for someone who breathes sideways - it would cramp their chest and reduce their breathing efficiency.)
If they do their job right, your fit will be as unique as you.
