I think they already tried their best to resolve the issue. They even offered you a replacement unit which is much better than other big companies out there. If I were you I will let them handle the RMA and send to their factory in China to make the necessary repairs. If urgent and need the laptop for work then just accept the new replacement unit which has better spec.

For reference, I had to RMA my Asus republic of gamers laptop before, it took 3 months and there was no reply from queries until my laptop was ready for collection.

If you are lucky you can get the laptop within 1 month. Otherwise prepare to wait at least 2 months due to shipping from China and back.

If you can wait then wait for the RMA unit.. otherwise just take the new unit which has better spec like you mentioned.
