there is so many mod to chose from i am wondering what mod is best to use to play this game.

So the game is fun to play that its not too hard and not to easy either

You can't just globally tell which of the hundreds of mods out there are "best". Especially since many of them are just visuals. How is your character looking like a demoness "better" than it looking normal ? It's a matter of taste/opinion/playstyle/preferences which mod is best for you.

Play the game and develop a preference for something or come up with "I wish this were different" and look for a mod that does it ^^

For example if you play the basic game and want to play with a full undead-only army you will most likely have the wish to be able to "revive" casualties during a battle. There's a mod that implements an "animate dead" spell that lets you do so.

But that's not the "best" mod, you know ? For somebody who doesn't use undead creatures a lot or none at all this mod would be entirely useless. See my first paragraph.
