Is there anything better out there?

I LOVE christian death metal and grindcore music and I am always searching for new bands that are really good. BUT i have come to the point where i want to know is there anything harder and better than death metal?????? Its starting to get to the point where thats not hard enough so if you know any good bands PLEASEEEEEEEE let me know. I really like bands that aren't as well known but are erally good and don't go giving me underoath, devil wears prada, norma jean, or haste the day. I am into more stuff like impending doom and woe of tyrants and ecryptor. so if you know any good bands let me know THANKS!!! :)
