Hicks
Ashton
are the top 3 with Riley next. 
Kevin Penny still the most exciting for those first few months though.'"
This isn't even a debate.  Ashton is better than Hicks was
Ashton is a lot faster 
Ashton makes more yards running it in.
Hicks was better in the air
Hicks was possibly marginally better in defence.
Ashton's finishing is better.
Overall, I can't see why people still go on about Hicks.  How many would Hicks score over the last few years for us playing outside the centres that Ashton has had to.  T King and Ratchford versus M King and Bridge.  This isn't even taking into account how dominant our pack was while Hicks was here.  So we we got downfield a lot easier and created more opportunities for our outside backs as a result.
