This is a toughie. i looked up wikipedia and it lists 9 main characters so i'll go with them and stick one more in to make up the 10 options although i think, in fairness, wesely crusher and geordie la forge could probably be safely left out of the top 10 and replaced with more worthy but more peripheral characters like the crystaline entity and lwaxana troi. my favorite i think would be ensign ro laren. i like the way she betrayed the federation in the penultimate episode and was loyal to her people. she was in some cool other epsiodes too.
although data maybe would be a better choice. i'll have to mull this over a bit... i didnt fancy any of them really so that wont affect my judgement.
