You have so many suggestions here, and cheesecake lasts for a little while if covered in the refrigerator so........
Maybe go around and get one piece of each and make a little score sheet with numbers or stars, like for a wine-tasting, and let him decide. You could have maybe 5 things to rate, like texture, flavor, sweetness (too much/too little/just right) -- can't think of any others......well, maybe quality of ingredients, crust......Is that enough?
Could be fun and then you would know the answer for future reference....or he might never want to see cheesecake again.
Oh dear, all the OP did was ask for the time and here I am building a clock.
