Miniloaders (redux) are better at balancing belts or belt lanes equally than most other loaders.
Firstly, if you make multiple miloaders unload from a chest to belts such that the belts are mostly empty and can carry away more output than the chest can supply, then each belt will get loaded an equal throughput of items. Other loader mods can't do this, they will often unpredictably unload some output belts with more items than other output belts. As far as I know, the only loaders that have this behavior is Minilaoders (redux) and therax's original Miniloaders.
Secondly, if you use a miniloader to load into a chest, and the input belts are mostly full, the chest gets emptied slower than the belt can supply them, then the miniloader will pull from the two lanes of the input belt equally. Most loaders from other mods will favor one lane, and if the chest gets emptied slower than one lane's speed, they will only pull items from one lane. As far as I know, Miniloader (Redux) is the only mod with this property.
These balancing properties are very useful. Especially together with large chests from other mods, miniloaders can replace most belt-based balancers or lane balancers with easier constructions. Because this is so useful, I think you should advertise this in the module's long description on the mod portal, and perhaps in screenshot images too.
Loaders combined with large chests also let you easily configure priorities between multiple input and output belts to any order you want, and it's easy to change these priorities. Multiple loaders load a chest lets you balance input belts equally, and a loader unloading a chest lets you balance output lanes easily. These are also useful, but they also work with other loader mods that use Factorio's built-in loader entity (starting from Factorio 2.0).
