In my opinion, All Eager Zebra Games are excellent to play on a daily basis.
All Eager Zebra Games pay you 5 MRP per 1 T-Credit used on that game, and 1 AVP.
If its the amount of T-Credits that you can ultimately win that you are concerned about, I would suggest checking over each Eager Zebra Game to determine which one has the highest jackpot for T-Credits for that day, or time period.
