Navy SAR vs USCG rescue swimmer?

I want as much info on rescue swimmers as possible. My recruiter told me that when I'm not out on a mission I would be in the gym working out. He made it sound like a dream job but the more I research the more I realize it is kind of lame. It won't be as much action as I thought. How many rescue missions do you go on a month? What is more of an intense training between the two? Explain your daily ruitine? I also want some combat training along with parachute training... should I forget rescue swimmer all together? Join SARC or USAF PJ? I just don't want to fail out and end up mopping floors on a ship for 4 years. I want action.
