Who is the strongest wielder of Mjolnir?

There aren't many Asgardian hammers, but there are a lot of users.

Firstly, the main users are Thor, Jane Foster, Beta Ray Bill, Thunderstrike (Kevin Masterson) and Thunderstrike (Eric Masterson).

The weakest users are both Thunderstrikes. They are less experienced and their hammer, Thunderstrike is weaker than Stormbreaker and Mjiolnir.

Now, the third out is Jane Foster. She doesn’t have as much feats and she only is smarter and has more control over her hammer.

Finally, Beta Ray Bill is out. He has lost to Thor multiple times but is a near equal.

In conclusion, Thor is the strongest enchanted Asgardian hammer user. Anyway he has Asgardian DNA meaning he is stronger.
