Default Noob question

I've been running a custom for the last week and read that some roms will be changing to NF3 base from Singapore. Have some questions please:

1. What is NF3 base
2. Will it make my n9005 run faster with better battery life
3. Should I stick with the none NF3 rom I'm using now
4. Love this site

Thanks people
