If you split the season into two parts, spring season/classics and then stage races.
Vino won the LBL, Hincapie won KBK, GP Poulay (protour) and came second at Roubaix (and 7th at Flanders). Vino gets the win in the classic but Hincapie shows consistency throughout the spring races, still wins two races.
In the stage races Vino gets stage + 5th overall Dauphiné Libéré, 2 stages + 5th overall Tour de France. Hincapie gets two stages at the Dauphine, one stage at the TDF (two if you count the team time trial). Vino beat Hincapie in both the ITTs at the tour. However Hincapie at the tour can't be judged properly as he was riding completely for Armstrong, whereas Vino certainly wasn't riding for Ullrich.
I retract any previous judgement on who had the bettter season, I'm not sure if I care and I think its quite hard to tell. All i'll say is that they are both great riders who, unlike a lot of riders these days, perform in both the Stage races GTs and the one day races.
