I've got a Ranger 2/Wizard 5/Eldritch Knight 3/Spellsword 1 in my campaign, and he's a great character.
He's gone for the ranged combat route, and has Precise Shot, Point Blank Shot, Rapid Shot, has created his own composite longbow of shocking and also makes very effective use of scorching ray, Melf's acid arrow and similar spells due to his high base attack bonus and ranged feats.
He's just taken his first (and only) level of Spellsword, which allows him to wear his mithril shirt without a spell failure chance. He has a good AC (a very high Dex score!), and really, really good Spot and Listen scores (about +23!).
His weakness is in melee, as you might guess, where his hit points are low (59 hp) and attack bonus and damage likewise. He stays out of it and is effective elsewhere. (In a recent adventure, he was drained for 6 points of Con and was running around with only 25 hp!)
The Practiced Spellcaster feat he has allows him greater damage potential from his spells, but the three levels of spellcasting ability he's lost really hurt him in terms of overcoming diverse challenges. (He has only 4th level spells when he should have 6th level spells).
How does he stack up against the other PCs in the group?
Well, the Dwarf Fighter 6/Dwarven Defender 4 is definitely the tank of the party, dealing a lot of damage in melee and being able to take a lot in return.
The Human Sorcerer (monte) 6/Mindbender 4 is the diplomat and main spellcaster of the group. She definitely has more firepower available than the Eldritch Knight, though the two work well together.
The Human Psychic Warrior 6/Pyrokineticist 3 is a newcomer to the group, as is the Human Paladin 9; both are weaker than the other three, but that might also reflect on the inexperience of their players.
Cheers!
I'm greedy like that.
