You really need to do more research if these are your concerns. Every American schoolboy has a hard on for SOF from video games and movies. Meanwhile, the reality of is obscure, even to most active duty servicemen.
How can you say that you want to be SOF unless you know what they do well enough to know the differences between them? You really need to do more research. Read The Warrior Elite and Chosen Soldier by Dick Couch. Then, read That Others May Live by Jack Brehm, and Blackhawk Down by Mark Bowden. One Bullet Away by Nate Fick will close it out for you.
If you fail to do even this basic amount of research, I'd bet my life (and yours) that you are not SOF material, because you took the easy way out: you dreamed, and did nothing more.
Edit: the guy above me is wrong. Recon BN is a USMC asset, not SOCOM. They are not techincally Special Operations Forces: MARSOC is.
