Define better? I use Caparisons (A Dellinger and an Angelus) and have another on the way next year. The biggest difference between them is the neck by and far. The neck on a Dellinger is larger and I find more comfortable to play as it has a nice transitional carve from a D at the nut to a C at the high end and has a wonderful feel under hand. The Jackson neck is very thin and pretty flat comparatively which I find fatiguing to play. Tone wood wise, both are available in a few different types (Caparisons do maple/mahogany and mahogany/walnut only though) so it comes down to what you want in that area.
I prefer Caparison as they sound killer for my needs and the necks are perfect to me plus there's a meticulous attention to detail on every one I've picked up however they're not for everyone.
