Only pick one!

I’ve had Embarrassment of Riches on repeat

This is such a dope release!

Have some Mach records and they are what I would assume the first pressings? What is the difference between the albums on zotanica now and the ones that were on his actual site before? Are these second pressings or are they just pressed now by a different label as before it was non label? Please be easy on me, I am somewhat new to Mach purchases without buying off eBay or discogs.
