Easiest vs Most Difficult Combat Style

How many actual character combat paths are there? Assuming you choose just one

What is the easiest and hardest?

Melee

1 Handed

2 Handed

Dual Weapon

Stealth?

Fists? Lol

Ranged

Archer

Stealth Archer

Mage

Destruction

Conjuration

Any good hybrid builds?

For me Stealth Archer is easy and I also enjoy lurking in the shadows. 1 Handed dagger as melee.

I've tried being a mage using destruction but seems very slow to level up even w the mage stone active. Maybe I use the wrong spell on the wrong enemies?

I've never tried conjuration as a main build.
