Why is drum module X ...

I lost sleep and appetite developing MegaDrum and due to exhaustion I've been loosing sense of reality. And this is why I'm asking this question:
Why is drum module X better than MegaDrum?
Here are some examples.
Roland modules.
1. Available to buy from a shelf.
2. Large army of followers.
3. Built in sounds.
4. Positional sensing on snare and ride (only TD-12 and TD-20?).
5. ??
