I've tried it all... from using a kick straight out of a sample pack, to hand-creating my own using white noise / FM / Kick audio content and topping & tailing. Recently i purchased Kick from Sonic Academy / Nicky Romero. I have not yet used it to any effect, I haven't had the chance, but i am eager to. I feel like my kicks could use more personality.
If you do spend time in the area of "I want to recreate that drum/snare by Noisia/Koan/Prydz/Ford/Xilent", then you'll be inspecting some incredible audio. The high frequency content they add in the first transient is such a huge part of the magic, it can make your head spin. This is a very clever art form.
Sample packs like Leviathan and VR can take you so far, but you will fall prey to standard sample pack fatigue. I tend to avoid these for that reason *except* drums like kick, snare etc... You can use them if you want, but there's no room to do parallel compression on them, or to do just about anything to them without distortion. These are finalized, finished sounds that take away any flexibility you may want. Still, these are good tools to making your own, as companies like Black Octopus are wizards in their own right and know how to make punchy, attractive drums.
I've spent some time and $ at WarpAcademy with Vesper's tuts on creating your own drums. Incredible information there, and an insight into the industry I never thought i would get. Vespers is up in BC where Black Octopus is (And Monstercat, etc...) and they have some level of interaction, so the info he gives about those experiences is priceless.
