Looking at the results of the poll that just finished, one thing is clear: Most people would like to see Linux moving to a single packaging format. Out of all voters, only 10% were happy with the current situation.
The next question is, if moving to a single packaging format, then which one? Surprisingly, most people agreed the DEB format, or a derivative from it, should be the perfect candidate.

As can be seen in the graph above, the DEB packaging format gets massive support when compared to other alternatives. In any case, I don't think it is wise to get too caught up in the "battle" of which one is the absolute best, but maybe acknowledge that it would be best for the OS and the whole community to use a single format and target that as a future objective.
Thanks for voting!
