This mod pack has a great number of mods. Some being...

Alex mods- adds new animals/ mods like bears, tigers, and more!

Minecraft animals are a huge part of the game, like pigs, cows, and chickens, but beyond that, there aren't many real-life land animals. This helps to create more variety.

Apotheosis- changes and improves the enchantment system.

The enchantment system is widely used but hasn't been updated or changed in a long time. This brings a more in-depth enchantment system.

Better End- which improves the end with new biomes and mobs.

The end has not been updated in a long time, so having this will increase more to do in the endgame.

Biomes O' Plenty- adds new biomes to the overworld.

The various biomes already in Minecraft help to accommodate what a player wants best. This mod helps increase this part of the game.

Iron Chest- creates chests that can hold more storage.

Creating a location for storage is great, but at some point, the player will lose space for the chest. This helps with that problem. To save time and space.

Create- adds tech to make machines.

For those who focus on automation for their farms. This creates more opportunities to do so. Think of this mod as an extension or different type of redstone system.

There are even more mods that improve and add gameplay to the game. It is best played with friends on a server!
