Any nickelsteel strings in .009 or .010 should be fine.
Personally I don’t like Ernie Balls at all, and consider Elixirs to be way too expensive (a single set will cost you something like 20% the price of your guitar).
D’Addarios are good, I’ve heard good things about DR. Never used DM.
Just try several different kinds and see which you like best.
String are cheap, replace them often. 3 months is a LONG time, 1 month is better.
