[Son of Númenor]

I don't remember Melkor using a mace. Wasn't Grond a hammer?

I think the most interesting weapon in Middle-earth was Gurthang, because it was the only one that had any sort of personality. Anduril certainly had a great 'presence' when it was mentioned, but the doom that hung on Gurthang, its unique & mysterious origin, & its interaction with Beleg & Turin, made it the most fascinating to me.

However (to answer the initial question), I do not think I would rather wield it than other weapons of Middle-earth, because of Melian's proclamation to Beleg:

There is malice in this sword. The dark heart of the smith still dwells in it. It will not love the hand it serves; neither will it abide with you long" (Silmarillion, "Of Turin Turambar").

I certainly wouldn't trust such a blade. If I had my choice of weapon (if we use the term 'weapon' in a very liberal sense to mean something used in the opposition of an enemy), I would choose Narya, whose power is not in might but in summoning the courage & kindling the valour necessary to overcome evil.
