Looks interesting, I see no limit on how many times one can use the BRG, I like the price match + GC, but you do need to complete the stay, 48 hour pre-file for claims done within 24 hours of booking (so you can't file a claim for a room you booked for staying in within the next 48 hours), card arrives after stay.
