No, better mics won't help, as a lot of the sound is not coming from the stage, but from the PA. These days, a lot of bands are trying to keep stage volume as low as possible, so that the engineer has more control over the mix. It looked like even Cradle of Filth were using a plexi glass shield on the drums.
Anyway, that's why one would normally record from dead center (rule of thumb: you and the PA forming an equilateral triangle) or inline with one of the PA stacks.
At bigger shows you will often see so-called infills, separate smaller speakers in the center that usually just provide vocals for the pit. In those situations, you might get good sound up front, but generally a bit further back will be better.
My first recording didn't sound half as good as yours, by the way. Welcome to taperssection!
