Well, it depends. Vana is good if you have time to go through all the lvls. It may be easier to do rise or fall or jelly king. Both get an average of 2000 to 3000cr each time. However, if you do jelly king, you can get the jelly coins or whatever they are called. Then you can get the 3 star items from the token vendor. You can then sell them to a snipe guy or whatever theyre called. They buy bound itme too. Ive sold those 3 star brute helms and armor before. They get you 7500 for one 3 star item. So, do about 4 jelly king runs and you will get like 10000cr with an additional 7500cr for selling the brute jelly stuff from token vendor. I use this theory a lot. So you can do Vana with the same process but it will take longer. First becuz you have to do like 3 or 4 levels i cant remember, and you will have to get like 25 almirian seals before you can get anything. However, one 5 star item give you a LOT of cr when you sell it to a vendor. I do jelly king instead becuz it is quick and gets you cr at a fast rate. So you will have to choose, Quick cr and like 17000made in profit, or slower process but more cr made if you are willing to be patient. I hope this lengthy answer has answered your question. I hope it will help you get cr. :).
