Well I'm pretty sure the discussion was about AT behaviour. The Embraer still beats the others hands down at that but it must be useless because it can't CAT III auto land OEI in a 40kt crosswind (what can?).
I'm also reasonably certain that when I was doing GNSS only approaches on it the RNP/ANP was probably quite small.
