First of all, welcome to the RV Dreams forums.  You will generally find lots of answers here in the forums and on Howard and Linda's overall website.

First time I've even heard of MASA.  If you are referring to MASA medical transport, then you have placed it in the right category.  If you are referring to masa meaning "dough" in Spanish, and thus cooking related, then it would need to be in another category.

I'm presuming you mean the medical transport, since you also mentioned FMCA assist.

Skymed and MASA are the main competitors and both sell to the RV world. In the past you could get a lifetime MASA membership, which gave many piece of mind and was the choice for friends. That was not available with Skymed. Both are more full featured than FMCA's offering, giving you more choice of where you are transported to, etc. But the FMCA offering is much cheaper and does the job for many. Both Skymed and MASA will badmouth FMCA assist, often trying to scare you. But, realize how much money they spend to recruit new customers, money that your fees are paying for. If you have pre-existing conditions, check the fine print on the contracts, including FMCA assist.
