Have seen the recent thread regarding the ACA J41 fleet reduction and it seems a mixed bunch of opinions of the J41.
From my time working with Eastern Airways in the UK up until the the end of last year (who are one of the largest users of J41's in the world) I can tell you the following:
Some of the senior flight crew (who had flown on other turboprop types for other airlines) seemed to be of the opinion that the J41 wasn't best aircraft in the 30-seat class.
Yet, the J41 seems to be one one of the most efficient 30-seat aircraft for sectors of 300 miles or less (or 29 seats in the J41's case).
Having stepped inside a J41 at Eastern Airways maintenance hanger at Humberside airport, the cabin does seem very small. I have flown on an SF3 and somehow the J41 seemed smaller.
I realise that there may be aircraft in the J41's class which may appeal more to business travellors than the J41, but is the J41 a deterrent or is it what you would expect from a 30-seat commuter aircraft?
