Jan is great from the banter perspective and useful if you need extra help in the mage or thieving areas, but eventually he just seems somewhat limited. Korgan rocks as a tank, and Mazzy is a fine archer, so if your main character is a mage or cleric, you could benefit from Korgan, Mazzy, and Jan in the party. If you already have a fighter type as the PC, then having both Mazzy and Korgan gets to be a bit tank-heavy.

However, I always find it hard to let Minsc go. Afterall, I had him in my very first party all the way from BG1 to TOB. And think of how sad Boo is when you send him to wait for you at the Copper Coronet, that's no place for a miniature giant space hamster.
