LED, but you shouldn't really be so worried about other peoples opinions. :D
"Best" is what you decide after you line up all the pros and cons and your needs and wants.
If you were basically unfamiliar with both, I would strongly suggest going toward LEDs because they are the future and they are much less expensive to own.
There's also a lot of hype, so make sure you ask a lot of questions and compare a lot of users tanks before you pull the trigger on anything.
And technically I answered your question, so I'm going to flip the script at the end: ;Happy
Have you seen any tanks that have lighting which stands out to you in a good way?
