My pick would be any of the link operators for the staff travel and because its all pax there is no back of the clock flying freight (been there done that: didnt fancy it much myself).
Dont forget to mention that despite similar/better pay you have to pay out the $$$ for ground course and type rating for National and Airwork with no guarantee of a job.
Airwork dont seem to work too hard which is nice but you are flying metros rather than the newer gear on offer with the Link carriers and if you intend to move on at some point that lack of total/command time from not having to work so hard may be a hinderance, you do however get to stay in the main centres.
Chats seem happy although being a fairly closed group can be a difficult circle to get into, not unlike Airfreight.
