I'm going to have to compare that Ratchet Rocket to the Alien II.

The tools I carry often vary depending upon what I'm riding, where I'm going, and a few other variables.
But usually a multi-tool of some sort, something to patch and pump tires/tubes, something to cut things with ( shopping bags wrapped up in cogs ), tire levers, and probably a few more things. Several decades ago I used to carry a freewheel tool in case I broke a drive-side spoke.
I also sometimes have duct tape and bailing wire in a limited amount.
