I used to have a FA35. I select it over a FA31 because I couldn’t swallow the 31 price. From my test, FA35 at f2.2 is about as sharp as the 31. At f4 – 5.6, my 35 is sharper than a copy of 31 I test when pixel-peep. And its overall image rendering is not that far away from the 31. Anyway, I still give 31 an upper hand for everything beside sharpness at f4 – 5.6 when pixel peeping. (of course it is a 3-4 times more expensive ltd lens.)
35ltd Vs FA35: If speed is your main concern, FA35 seems to be a better fit. And you mention about shooing a concert in low light, keep in mind the 35ltd is a macro lens if it misses focus, it will do slow hunting. Every macro lens does this. It can be annoying. On these regards, FA35 could be again a better fit.
But personal speaking, If I have to select a 35 mm again, I would go for 35 limited this time because I like night city landscape and do 90% of the time on a tripod. 35ltd produce better looking starburst + of course a better build.
