I have not worked for either, but I have dealt with both. Like everyone else said, it depends on what is important to you. I do take insurance, so the cost and types of insurance available is part of what I look at since I have prescription meds and see the doctor every 3 months. Also look at who has long and short term disability, because when I first started I travelled with Preferred Healthcare/ Nurses RX for 2 years, not realizing that if something happened to me and I had to take off for awhile, I would have to rely on my savings because the company didn't offer disability. So now I really pay attention to that. Plus some of these companies that do offer insurance for free have crappy coverage.
Cross Country has lots of assignments, but has shared housing and lower hourly pay. Fastaff has private housing, but you have to beware because they staff alot of "Crisis situation" hospitals, which most take you just by looking at your profile and don't even interview you. I have found that I never go anywhere that doesn't conduct phone interviews since most of those facilities are hurting for nurse bad and don't treat travelers very well.
is a magazine with a lot of info just for travelers and has a lot of companies in it to contact. I tend to chose companies based on private housing, insurance, and rental car. I don't wanna put any more wear and tear on my car, I only go with companies that provide it and all inclusive housing that has linens, pots and pans, vaccum, etc. I hope I helped you out in someway. LOL. I wish I could have asked someone before I started on what to look for in a company and how to put things in my contract. I have learned alot along the way thats for sure.
