What are the benefits of legendary skills?

I got pretty much all of my skills to level 100 on Skyrim, and now, I have the option to make them legendary.
I searched on the wiki and found that this will reset my level to the initial value i.e. 15.
I have also downloaded the skyrim community unlocker mod, which increases the level cap from 100.
So, my questions shortens to- Is it beneficial to turn a skill legendary and get all your perk points back, or continue with leveling up with the help of the aforementioned mod I have installed?
I want to level up fast (The character level), so which one of the above would help achieve my goal with better efficiency? Also, are there any special items you get once you make all your skills legendary?

The net benefit in the end is more magicka/health/stamina, because you'll have to choose either one when leveling up. Depending on your game-play style, this could increase the fun.
Spells you once learned, will always stay learned. When making a magicka depended skill legendary, you'll notice that spells will take more magicka to cast. If you are a higher level with, say, 600 magicka, you will be able to cast high end spells on a low skill level.

Are legendary skills stronger?
A skill can be made legendary multiple times. While it doesn't make the skill any more powerful, it does mean that players can keep leveling up that skill, which counts towards their character level.How do legendary skills work in Skyrim?

Answer 2
Making skill legendary benefits you in way, that you can get levels and perk points again by leveling the same skill again.
The best one is Alteration because of this (sort of) exploit. If you enchant your gear to have lowered alteration cost by 20% (you need grand soul gem with grand soul) and enchant 5 pieces of armor, the mana cost of your alteration spells is gone.
After that is done, get telekinesis spell and pick up some random item like plate, hold it in the air with telekinesis and fast travel across map. Boom, your alteration level is instantly 100.
Make it legendary, rinse and repeat until satisfied.
