Question about Marine Corps Service.?

I have heard conflicting reports about army and marine pay, bonuses etc. What is the truth is it equal or what? Also if i join marines, my ultimate goal would be special operations can i go in to army SF or AF para-rescue?
Update: im not doing it for money im making more money now anyway. Im doing it cause i want to serve, i just want to know the truth before i get into it.
