It
shouldn't make a difference, but if I was swapping from Ultegra to similar quality mtn component, I'd go with XT 7xx series FD. The 443 FD you describe does actually sound like it's defective, but some of the newer Shimano stuff in the past couple of years has been slightly more particular about setup. I'd swap out another mtn derailleur as part of diagnostics, Deore or SLX if you don't actually want to go all the way to XT level component.
