So back into the point, if you're cheesecake lover (Duh, if not you won't be tempted to try), you definitely got to try this! But bear in mind, Japanese cheese cake and American cheese cake such as New York cheese cake, marble.... is totally different! From the texture and the amount of cheese they used.
American cheesecake is more moist and more cheese in a spoon, it's like mouthful of cheese.
Japanese cheesecake is very light of cheese, mild, and milky while the texture is soft and fluffy.
Depends on your liking, personally I think both are equally good and nice! For light snacks definitely Japanese cheesecake suit my liking, however, for brunch or evening high tea is always american cheesecake.
I can totally finish a whole Japanese cheesecake! Due to not too cheesy and just nice light flavour, it's not like if you have too much you would feel like throwing up, not for this!
Lastly, is this worth? Yes I would say, I always don't believe on baking my own cause the cost and time is more than what it cost and most important is no taste guarantee. Haha just saying but baking is sometimes fun... until the amount of dish washing...
