Note that some of these are based on preliminary measurements and listening tests. If you find contrary evidence, please let us know and I will recheck.

Tone Projects Kelvin: An amazing little plugin that so far (to my ears and measurment does harmonic distortion right — without aliasing at any sample rate.

Leapwing Dyn One 3: Very little aliasing in parallel comp mode. Tested at 96 kHz sampling.

PSP OldTimer MB: Very little aliasing. Tested at 96 kHz sampling. I use this plugin very frequently when mastering from stems. I have NOT used nor tested its tube emulation option.

The  Tone Projects Unisum measures totally free of aliasing at any sample rate. Remarkable.

I can certainly agree with those four!

To me the big test is what happens when it gets downsampled to 48 or 44.1. I assume this is about the quality of low-pass filtering and never going for maximum bandwidth at high sample rates.

What about eqs? Have you checked out the new Sontec by Make Believe/Metric Halo?  Bob (Katz), many years ago I asked you why when I put on almost any plugin (with the exception of sone Metric Halo stuff) it always immediately sounded worse (or louder and worse like the UA stuff). I was new to DAWs having been mostly analog. Your answer was complicated and over my head. But I appreciated it nonetheless.  Feel free to moderate my comment right out of this forum. Miss you. 🙂

Bob, how do you test aliasing?
