BlackHole has a lot of options installed and most would say it is a full image. This is great, but the more you have installed, the slower your overall speed will be. There is an option in Black Hole to eliminate things you do not want or need.

OpenPLi has a good set of basic features, then you are expected to install the options you want or need. OpenPLi does not have the beautiful boot screens either, but you can change the boot screen if you desire. I also like the Hotkey option in OpenPLi. Hotkey allows you to map the keys on your remote to your liking. Several other images have this feature, but under different names.
