Zero Difference the dealer will stand behind the new bike warrantee ... I only have a Trek dealer in my town lifetime of original owner, 1 year on components

These days Trek has Giant make their bikes under contract , following Trek's designs /parts picks.

FWIW, that was going on long before Giant started setting up their own Dealer distributor Chain around the Globe.

By now, They really are Huge.. Merida ia another Biggie , in contract bike Manufacturing..
