I think lovemesweet cheesecake is far better than uncle tetsu's.
I find that it tastes a little denser than UT, like a true light CHEESEcake where you get more of the cheese taste.
On the contrary, when you get uncle tetsu's cheesecake, it tastes more like a spongecake than a japanese light cheesecake. It does slightly get better after refrigerating it for a day, but you still taste the strong egg flavour. Not to mention the ridiculous waiting line.
Both cheesecakes taste better after a day or a couple hours of it being in the fridge.
But yes, LMS is miles better than UT's
