OP does have good fights but they're off-paneled at times and there's better alternatives for people who just want to see good/entertaining fights. The main selling point of the series is the story-telling, world building & mysteries it has.
HxH has the best battles in all of shonen, they rely on strategy and it's not always about who has strongest nen who will win the battle. It's all about outsmarting you're opponent. Skip to 1:25 it perfectly sums up HxH battles and how all battles should be like in shonens:

Togashi is the god of battles/fights in shonen so watch HxH 2011 anime if you want a shonen with good fights. It has the best and most consistent fighting system. Oda's true strength lies in story telling and world building. There's only a few shonens that can compete with OP in that department but I haven't read a series that's overall better than OP. Just my opinion tho
