I would think
last year's answer (re 28k TCs) still applies. (Though there's no upcoming 10x bonus day in the current promos listed.)
Each $200 bet at VP should be 1 Express Comp, and it's the same 75 TCs per Express Comp as poker. You have to earn at least 5 ECs to get any, but I think you still get the TCs if you don't meet that.
Whether or not Platinum is a worthwhile goal sounds like it depends on how much time you spend waiting in lines there, and how much importance you place on the entertainment opportunities (shows, pool, spa). The
benefits chart (click on Borgata at the top) doesn't make a great case for it.
