What do you want to do with it?
Personally, the Reising would be at the BOTTOM of my list. They are notorious for not running reliably.
The Mac 10 /11 would be next to the bottom of the list. You really can’t do anything with these other than spray and pray (although I will confess that I’ve seen some highly modified Mac 11’s that shot pretty well).
A M3 Grease guy is ok, but it was designed for tankers to use and is a close in weapon.
S&W MK76’s also had reliability problems.
Money not an object, the HK MP5 series is hands down the best sub gun to own. Next up is a Colt DEA 9mm.
Swedish K’s (Port Said’s) are an excellent mid cost subgun. Simple and reliable.
MP 38’s and MP40’s are excellent sub guns.
Thompsons are great. Heavy, but great. Lots of support for them too. Originally WWII M1’s are worth more than the post war “West Hurley” Thompson’s.
Sten’s are simple and reliable. Not much for distance shooting though. Sterlings are not as common but also not bad.
Uzi’s are a good gun. They don’t shoot as well from the should as a MP5, but in general they are a high quality gun.
Of the gun’s on your list, my top two choices would be either the Thompson or the Uzi. Original IMI Uzi’s are with more than the licensed copies (Vector Arms).
I’m sure that I’m forgetting a few - this is off the top of my head.
BTW - American AR180’s are a hoot to shoot. Though to get parts for though if you damage the magazine.
One other benefit of the MP5 family; if buy a sear gun then you can transfer the trigger pack across multiple HK’s. That give’s you not only a FA sub gun, but putting your trigger pack in an HK91 gives you a G3. You can also buy an HK93 and put the trigger pack in it for a FA .223.
