I gave up on the anime ages ago, but the manga is as fun as ever. It seems to be finally nearing the end of the current arc and while it has been an interesting one, it has also been super damn long. it's been 85+ chapters and over two years since the start. The anime and manga are both in the same arc (the one that followed the Dressrosa/Doflamingo arc) with the anime about 30 chapters behind the manga atm. So my advice is the ditch the anime and just catch up with the manga. I am not sure where you stopped, but chapter 801 is the end of the Dressrosa arc so that might be a good place to start.
