Are Standard Drum Samples Good Enough?

As I was continuing to work on a song/track of mine this evening I went into the unbiased (or as close to unbiased as a producer can) view of my track, listening to it as a whole, and as individual parts/ instruments. I soon found myself dissatisfied with the sounds of my drums throughout the entire track. They seemed weak and so fake sounding even for being dubstep, electro drums. I went through each drum and tweaked them a little and a little more and found myself still unsatisfied. I then decided to address the root of the problem, the drum samples themselves, I was using the standard kits you find in any DAW the Logic kits in this particular case. Realizing that my tweaking and adjusting were not giving the desired results I began sifting through the internet looking through forums, blogs, how to's, and so on searching for my problem and what I could do to fix it. I soon found the answer through many sites, my samples were just not good enough it was as if I was building a house on a weak foundation and trying to paint it just for the aesthetic appeal, so I could say "well they look good". Now mind you not all drum samples found in DAW are worthless and they can create just the sound you want. But building a beat off of drum samples made specifically for the genre of music you are creating not only saves time, it gives you more options to tamper with when you do get the overall sound you want. The beat to the song sounds so much better and sets it apart gives it a fresher sound compared to my other tracks. And I still have so much more room to tamper with them when I start to master the track. Drum samples are yours god enough, or could they be better?
