Purchase Advice J68-PL vs J68-GT

Looking to buy my first Acronym jacket and trying to decide between these two,

From what I understand the PL will provide more warmth and the GT is fully waterproof? However the length seems to also be different so the PL will provide more coverage as the GT?

Also I am 188cm and wear size L in most jackets (Arc'teryx, Norrona etc) so I guess these will fit similar?

Thanks :)
