Differences between new 12 inch single box set vs go go round this world box set (vinyl)?

Hey there! New to fishmans this year basically and wanna get their stuff on vinyl. For the price I’m just curious if it’s worth it to get the new 12 inch singles set or to just fork the money over for the go go round box set? I wanna get their discography on vinyl so I’m not opposed to getting both in time. My worry is the natural increase in prices box sets often have. We are not talking about fishmans rock festival lol.

Do the singles have unique versions of songs or can I get all this material on the go ground box set is basically my question thanks :)
