Gifts are more frequent at Ocean but higher quality in general at Borgata at least for me. My free play is higher and feels more frequent at Ocean than Borgata. My hotels offers are about the same at both. I earned status and tier credits faster at Ocean than Borgata for similar level of play. There are my views and opinions only as everyone's experience is different. Recently began splitting time between Borgata and Ocean with a little Hard Rock.
I was a CSR Diamond for many years before moving to MGM/ Borgata about 5 years ago and I never looked back.
