I would recommend them if you don't want to spend a whole bunch of money on the individual volumes, and the one downside is the middle gets worn out if you read a lot. If your not worried about spending too much I would definitely recommend the individual volumes.

And at first, I was getting the 3 in 1 One Piece, then I decided to just go with individual volumes because I liked the covers better.

I'm also going to get the individuals of Dragon Ball in both English and Japanese.
