The bad thing about a level of cleric is a whole level of odd (and few compared to ranger) skill points. The goods are the spells and saves. Another bad point is the BAB loss.
Overall, its a good deal for the feats, but the human fighter can do just as well (fighter feat + human feat = 2 cleric domains), and the fighter isnt locked into worshipping a particular god and all the other cleric baggage.
With 3.5 on the horizon, the ranger will become yet another good 1st level variant (though he doesn't gain a lot of steam till 2nd, with the combat paths).
