HMT55 over US300 all day. Find a PSA 10. The print run is smaller and the PSA pop is smaller on the HMT55. Chrome is king.
Now, if you have a budget of $800, you’ll want to find a parallel of Soto. In this case, any US300 or HMT55 is a win. You could find a nice Rainbow Foil US300:

or maybe scoop up a Short Print (hands on hips) variation:

Or even an HMT55 Pink:

Regardless of what you buy, make it a parallel or variation. These have a smaller print run and can be harder to come buy. It’s possible you can pick up a Bowmans Best Auto too, but that window may be closing soon. Good luck and feel free to reach out here or in the Juan Soto thread!
