Thor's been through Ragnarok like 3 or 4 times that we've seen, with a whole lot more implied. It's just a cyclical death/rebirth in the comics, not the end of all things that the myths say.

Mjolnir is way better than the lasso of truth, for my money. The lasso of truth is exactly what it says: a lasso that forces people to tell the truth. Mjolnir is a hammer--so right off the bat, it's a more practical weapon--that can absorb and redirect energy, mess with the weather, create portals through space and other dimensions, return to the user's hand no matter what, etc.
