If you liked Smart Lighting, the Simple Automation Rules app on Hubitat begin as basically a clone of that SmartApp's functionality (in fact, it used to be called Simple Lighting). I would suggest looking at it if you haven't already.
Motion Lighting has been around since the beginning as a more powerful alternative to what was then Simple Lighting. If Simple Automation Rules is too simple for your needs and Room Lighting too much, I'd suggest looking at that instead. (It is unlikely to receive future development like Room Lighting, but if it works, that shouldn't be a problem.)
I wouldn't suggest anyone do most motion lighting automations in Rule Machine, but that won't stop everyone. (And historically, Basic Rule is newer than all of these apps except Room Lighting. It will work for lighting automations -- or whatever you can build with it -- too, and is easily imported into Rule Machine, but as much as I'd normally suggest ignoring Simple Automation Rules, its origin with lighting automations in mind might give it a bit of an edge there.)
In order to simplyify, they actually did try removing some of the older apps for new users at one point (existing install that had them were fine), were met with negative feedback, and thus reinstated them for all users -- so at the moment, there are a lot of options because of history. Different ones may meet certain users' preferences better than others.
