Why are there two different mods?

The main mod has become too large for me to update for different versions of Minecraft.
Many people have found that the main mod has too many features that most Minecraft players don’t need.
The light version allows me to easily add new weapons from versions 1.16 to 1.20, but it won’t receive any other updates.

What are the differences, and which one should I play?

The main mod includes all features, effects, entities/mobs, structures, map creations, and blocks.
The light mod only includes weapons and armor with minimal optional effects.
The main mod focuses on staying up-to-date with all new content.
The light mod will only be updated if new weapons are added.
If you just want a simple gun mod, then the light version is what you should choose.
