I had so much fun (and a fair bit of success) with Lugia-EX back in the day, but Lele just does its job better, though deep hurricane is a pretty sweet move when you get to use it.
EDIT:
That said, I'm still using Lele as a major attacker, and I think Lugia can fill a fairly similar if not identical role - does have that fighting resistance and second attack. (and I did have some success with it until I *realized* how much better Lele was.) It's very well poised to benefit from fury belt and max potion - 210 is hard to hit, and it can hit fairly hard for a single attachment. Though muscle/choice band gives you better numbers with deep hurricane. I played it with Garbodor and Pidgeot-EX - those fury belts force field blowers and trashalanche takes care of the rest (still run that deck in expanded, but with Leles in Lugia's slots.) Another nice option is to run your own sky field with bronzong or malamar and use deep hurricane to clear out Shaymins and other vulnerable pokemon.
