You know, I've heard this concept that clerics are better fighters than real fighters, but I just haven't seen it in real play.
In one game, I played a dwarf cleric. He did decently in combat, but the PC fighter rocked. My cleric never was equal to the fighter. There was at least one adventure where my cleric had run out of spells, but the fighter could just kept going and going.
In my current game, there is a barbarian 1/cleric 6 and a fighter 6. Though the barb/cleric does well in combat (and was the primary frontliner before the straight fighter joined the group), the fighter does as well or better. Two attacks/round, cleave, whirlwind, etc. makes the fighter a powerhouse in melee. And in this case, the cleric even has a higher Strength. And both characters use a greatsword.
In both games, the cleric was and is vital to the groups' overall success -- keeps them patched up and has plenty of buffs and protections for support. But in straight up fighting, the fighters stand a head taller.
