Better???
Depends on your needs.
If you are heading into CAR for 30 days buy GR "save your ass" coverage.
If you have great medical insurance (from home) and are hunting close to civilization, i.e. hospital
do you need an evac package?
They are similar. NOT the same.
Depends where you are hunting and what your personal story is. (Health wise, accident prone, etc.)
Biggest difference GR will come get you, if required. (Depends on the plan.)
MJ you have to get yourself to a hospital and require inpatient treatment, then they'll get you home.
Although they used to come get you in Southern Africa from an airport.
Check the details and match it to you.
Thus far, I have used MJ.
All I've ever needed was some ice compresses, aspirin and once a tick fever treatment by the local doc. (Knock on wood)
If I go anywhere I think might be a bit sticky, I'll be getting GR coverage.
That's for me though.
