I don't know if this was already talked about, but I would like to hear some pluses/minuses of one over the other. For the purpose of this, lets make the character a 20th level character (Really trying to plan it out). My thoughts are for the characters would be as follows.
Bladesinger - Fighter 4/Wizard 6/Bladesinger 10
Duskblade - Duskblade 20
Ok, as of so far, I have leveled a Grey Elf Wizard to 5th and took 1 level of figher. I intend on taking 3 more level of fighter, then taking the 10 levels of Bladesinger, then one more wizard. I figure this route will give me 6th level spells - 6 caster levels of wizard plus the 5 caster levels from the bladesinger. But is the Duskblade a better route? What would I gain from playing a duskblade? What do the rest of you guys think?
