The revelation comes as a major surprise when you consider Alonso's title-winning exploits with Renault in 2005 and 2006.
But his remarks clearly underline his depth of feeling with Ferrari after joining the Scuderia at the start of the year.
"For me personally it's been a great 2010 Championship driving for a new team," said the 29-year-old Spaniard.
"From day one there has been great integration with Ferrari. I've felt very comfortable.
"It has been the best year of my career so far, a great experience and I'm very happy."
The crowning glory for Alonso would be to become Champion for a third time, but he concedes even if that failed to happen it would not take the gloss off his year.
"In terms of happiness, motivation, driving, the team itself, it's my best season," said Alonso, ahead of Sunday's Korean Grand Prix in which he trails leader Mark Webber by 14 points.
"It would be nice to become Champion this year, but if we cannot do it, I will still have great memories of 2010.
"But with three races remaining we will do our best to arrive to a position in (the final race in) Abu Dhabi still in the fight.
"We've made some good steps forward in the last five to six races, so it should be an exciting last few races, hopefully making the most of every weekend."
