Mint Choco Cookie is more effective than Cheesecake Cookie, but Cheesecake itself is already a very very effective way for coin farming.

Looking that you only need to buy 8 remaining cookies with coins, and few requirements that you can try to achieve, I think the only reason you will buy with Crystal is when you're totally bored with Cheesecake Cookie.

Tips:
 * 160 friends: add more friends!
 * 21 +8 cookies: use your existing 23 cookies, especially lower levels
 * 16 +9 treasures: you can upgrade C-grade treasures or Reverse Valentine's Day Coin Candy it's very cheap to upgrade!
 * get to lv. 60: depending on which level you are currently in, it can be achieved with natural playing
 * 5 evolved treasures: you already have 3, and you can buy lower level treasures with 5,000 then evolve with a cheap price too.

Don't forget we still have future cookies coming ahead!
