Yeah "hardest hitting drums" is a little too vague. You can make drums really loud, really punchy, but each of those has its own drawbacks to the rest of the mix. I assume what you want is stuff that cuts through the mix well, that means understanding where each drum stands in the frequency spectrum. By cutting out specific spaces for your drums to sit using EQ they become much more punchy (you hear the initial slap better, often referred to as the transients). This takes time to learn how to do it well, first you want to make sure you have your "go-to" EQ that you know in and out, use that as often as possible so that you get to know it as best as you can. Parallel compression can work really well for this too but it can quickly get out of control (your drums sound insane but getting the rest of the mix on par can be difficult) so I would use that experimentally at first, rely more so on really good EQ techniques. Also ducking the track (or at least competing frequencies) with the kick especially can help it cut through. Ducking is where you set a compressor that acts on the rest of the track (side-chain compressor) based off when the kick drum comes in, quickly compressing the rest of it for a brief second (fast attack / fast release) then bringing the levels back up, allowing the slap of the kick to artificially cut through the mix with less EQ needed.
