Ace Trucking only really had that one very bad, very long story - the Garpetbaggers. Sure, not everythinig before that was top tier, but it was always fun, and at its best it was just a glorious mix of character design, weird alien beasties, and surreal/hilarious dialogue - that somehow always made sense, even though I only discovered the 'Handbook' in a back Prog after I'd been devouring the strip for a couple of years.
Havn is perfectly good, perhaps a touch too cynical for my tastes.
Ace Trucking Co, and it really could go a long way...
