Which Map should I get?

Xbox currently has a sale going on for a lot of DLC. I recently bought Askiy Ridge and enjoyed it but im looking for something different now. Im between Yukon Valley and New England Mountains.(I like open maps) so im trying to figure out which one is more open. Anyone have any info from personal experience? Btw im gonna get the Modern rifle pack too and am wondering if there are any other packs that I should buy?
