With everything I've driven, I feel port injected motors have smoother idle and low rpm drivability.

I feel like you're talking about two things that may not be correlated. There's not really any engines that exist with/without DFI in total absence of any other changes, so it's really hard to blame direct injection conclusively. I've gotten plenty of miles on BMW N52, N54, N55, S54, and S55 motors and I don't feel like the low RPM smoothness is any worse at all with the DI motors on this list. My M2C with S55 has a smoother idle than my Mazda MZR 2.5 with port injection lol. I've only driven a 997.1 C2S of 997s so I can't comment about Porsche unfortunately.
