I need your help. I'm down to two SIP companies that are very close in price. I'd like to get your input on pros and cons you can think:

Option one:
6" PUR wall claim R-41. Can use standard jambs for windows
T&G on edges of panels composed of ripped 2x lumber that frames each panel. (extends on one side of panel, and recessed on other end) Caulk and nailed connection between panels

Option two:
6" PUR R-40. Need jamb extension for windows.
T&G on edges of panel composed of foam extending pass the plywood into cavity at end of other panel. Gasket and staples on the connection between wall panels.

Any opinions? Thanks!
