First, your user name is incredibly offensive. UPS is a good company, even though it wasn't the right fit for me. The drivers are really nice people (mostly), and are pushed to work much harder than FedEx drivers.
To your question: I'm a pt courier and kept the Blue Cross plan my wife has because it was marginally better. If you've got no coverage, paying for the FedEx plan is far cheaper than not being insured.
But I do have the dental plan. Well worth it. Also vision, which I'll be dropping.
