Maybe you could describe the workpiece and its intended
(ab)use.
Sometimes dissimilar metals are better off brazed.
What does "not good" mean, for the welds? Ugly, brittle,
??? Are you sure this is not settings or shield gas, more
than metal related?

309L is the correct rod. Your "steel mig wire" I'm guessing is ER70S-6...which does not contain the proper amounts of nickel among other elements to make for a sound weld. It will be brittle and most likely crack after multiple heat cycles, IF you get good fusion to both parts. There's a good chance it will never give you any trouble, but you asked what was right, and 309L is right....i have a 10# box of it I need to burn now that you mention it....

309 is the proper wire.... its my usual all metal wire. Its harder to find then 308..... that said, I have welded mild steel perfectly fine for non critical apps with common 308 wire.... mostly because it got loaded on accident and I didn't know until the reel went empty.
