.. with an accuracy of tens of miles

Probably not an alternative if you need walking directions to the coffee shop, then.

well there are no coffee shops in the middle of the ocean...

... but would you like a cup of sea?

That was LORAN-A. It would get your ship close enough that you could see your destination. LORAN-C was comparable to GPS with selective availability enabled. eLORAN will be almost as good as GPS.

Fun fact: the US Coast Guard used to have a base in the Oklahoma panhandle. It’s sole purpose was a LORAN transmitter.

I rather say before GPS there was Transit (aka NAVSAT). Which was the father GNSS system of GPS.

LORAN is ground based so it's like comparing apples with oranges, yes they are fruits.

GPS is a satellite system while LORAN is not.
