I have suspicion that GTPGA was targetted to Australian investors who can use the franking credits, whilst GTPGB may have been for oversees investors where franking credits are useless, hence higher (but unfranked) rate.
A sig factor though in total return is time to reset, you get $100 back a year earlier with GTPGA.
I cant rate GNS (know very little). Of the others I would put TIM ahead of GTP. WFL a bit of a dark horse, there may be significant upside or downside in their ethanol plans - time will tell.
