o1 or eb1 ?? any one of those 2 easier to get?

I want to apply for either o1 or eb1. I know that eb1 is for green card long term and the other one is part time.
Does that make o1 easier to get than eb1???
I do not have an employer, I apply as an extraordinary athlete.

O-1 would require a sponsor (employer). You cannot get O-1 on your own. Besides, this would hardly be any better than the status you had when you entered US to compete in the past.

Eb-1 can be self-sponsored.
