Oh yeah. Mudkip was easily the best starter. With him, grab a shroomish (he evolves to breelom, a plant/fight hybrid with good quality in both) and your setting yourself up to counter lots and lots with that dual typing. Meanwhile, zigzagoon sits at level 3 FOREVER, and picks stuff up off the ground all day, while knowing 4 HMS (actually, I recommend working to linnone. He picks up better stuff).
Oh, look! Got a slakoth. Yes please. Honestly, a psychic covers most bad holes from there.
