I prefer a specific tool for each job. Like a jack-of-all-trades, a gun that is good for everything is master of none.
A dedicated Skeet gun, like Zippy uses, choked, balanced and stocked for the game will always have that edge a comp shooter is looking for to get that one extra bird which can mean winning or losing. The same holds true for those who shoot trap, flyers, bunker, etc.
Even for my favorite, sporting clays, where the chokes can have the most versatility, many folks stick a certain combo in their O/U or a LM in their semi and don't change
