I will add that exact noise specifications should of course be included in the datasheet of any given part.
Given the nature of the beast (bipolar transistors running at fairly high bias) I expect CFA voltage noise to be quite competitive, but IN+ current noise may be a few dB higher due to the combined base currents of two transistors. Off the top of my head, not sure how much current noise there is on IN-.
Many integrated instrumentation amps use current feedback in their first stage to achieve stable performance across a wide range of closed loop gains. Some of those ICs exhibit very low noise at low source impedance.
