I have read several news sites about Systemd and how better it is but I have not yet seen one that actually compares Upstart with Systemd. Actually, I haven't even seen one that talks about the benefits of Upstart. So a point to point about the differences, advantages and disadvantages of SystemD and Upstart would help.

Right now, all I know is that Upstart was developed in Canonical and was ported to other Distros. That is all.

Of particular interest to you will be:

Upstart was written for performance and reliability from the outset. It is also revolutionary compared to all other init systems available today:
