It’s a good set, but after Crown Zenith, Vmax Climax - it makes the Triple Beat pull rate seem low. Get about 10 good pulls in a box, so it’s worth it. You’ll end up with more duplicates than usual in this set. Overall this is a fun new set for Pokémon, superior quality and QC than other regions.
Triplet beat is a great pokemon TCG set if you like Japanese cards and/or the Scarlet and violet Pokemon, particularly the starters as all 9 evolutions have really great Full illustration cards. This box will likely include most of the set within it, you might be missing a basic card here or there but you can easily buy those individual card you are missing. Japanese boxes also seem to contain more rare cards but that's just my guess
