I'd love to hear your thoughts between the two.

I mean its seems to be close to MAP 1 and 2 depending on how you set it ( and feels like it to be honest). I switched to the JB4 so I can datalog and run some higher % E85 if I wanted to.

Map 2 is equivalent to 3pm dial on JB+ I assume. 4psi~

JB4 Map 1 is very close to JB+ (max setting) see dyno below

But IMHO , as i have used both , the JB4 is "smoother" and has a host of other functions.

BUT If you are gonna use car bone stock and want something that takes seconds to fit and remove then a JB+ is a better option.

Max setting on the jb+ is 4.5 psi though? Map 2 is 4psi on the ib4.

But ... the JB4 also has many channel inputs from not only TMAP but also MAP and ODB2 feeds inc revs/gear/temps/trims/timing etc ... JB4 will be a more "educated" map than purely adding boost.
