I did like Hope. He was very realistic, and I really felt for the poor guy. Hell, I was cheering him on to get Snow!(More cause Snow annoyed me, rather than the story reasons) and I must agree, the scenes between Lightning and Hope are some of the best in the game(Except for the "There's no hope for l'Cie!" "There's you." line, which made me groan, even though I could see it coming) Vanille and Snow were the two who annoyed me, but not really for story reasons, but Snow's constant "SSSEEEEEERRRRRRAAAHHHH!!" and insistance he was going to save everyone, and Vanille's everchanging Australian accent(She got that region's accent right sometimes, as it's a fairly British sounding Australian accent in the South East part of Australia, at least, near Canberra and Sydney) the random slips into british and american accents annoyed me even more when I realised her voice actor is actually Australian. On the whole though, I felt all of the main cast were fairly believable and realistic, as much as you can be in a fantasy game
