I have the Paris and Swiss and I think it was completely worth the money, It was cheaper than my textbooks yet It is bigger than them and I spend more time on the photobook than my textbooks
I also have the Best of the Best Album that came with the photobook and I recommend that one too, The pages on both photobooks feel nice, although I admit the best of the best photobook feels smoother. Either way I recommend both
All in all, if your looking to feed your eyes I would recommend the Paris and Swiss Photobook and If your looking to reminisce with your ears from the beginning of T-ara and haven't been able to afford all the albums then I recommend the Best of the Best Album.
Yes I agree Haha hopefully this will tempt you all
Anyways, enough of my long-ish post, I hope it has contributed to helping you guys pick whether or not to buy these photobooks
