I don't know anything about the other tyres but I changed from Pirelli Dragons (190 on the back) which were a source of amusement to several club members to Dunlop 270s Race Replicas which Dave Cook recommended and they're fantastic. Brilliant on the track and the road, as far as I can tell. The 180 on the back makes a huge difference to how the bike turns. It's so much easier I can't believe I put up with the 190 for so long....
So I'm probably no help at all, sorry.
