Time to have a crack at a big anime and this time it's the best shonen series not to be serialized in Shonen Jump. I am of course referring to Fairy Tail.

Fiore is a world full of wizards of all ranks of power and alignment all split up into Magical Guilds that keep the peace of the lands going. Wanting to be part of Guild life herself, Celestial Wizard Lucy aims to join the Guild Fairy Tail which leads her to a fated meeting with the Dragon Slayer wizard Natsu who himself was drawn to the port town in search of his adopted father, an actual Dragon named Igneel. From that meeting, Lucy finds herself among other high powered wizards such as Ice Maker Gray and Knight Wizard Erza as they keep the peace from the evils of the Dark Guilds.
It's very easy to write off this series as a One Piece with wizards but all the things it does often surpasses One Piece in quality; to give a fair assessment lets compare the two.
Characters
Many of Fairy Tail's cast start off as being strong and remain that way throughout so there's less emphasis on simple powering up and more time dedicated to character develop, One Piece puts too much time into being creative with it's powers that they ignore the weaknesses of the characters they develop.
Villains
Both series seem to have the same problem with it's villains, for every good villain they have, you have to put up with at least five bad ones; while many are creative in design, their personalities along with their motives are a bit silly and do little to move the plot and function as a punching bag for the main characters.
Spectacle
Fairy Tail always manages to end each arc with a bang and even some of the side villains go down in spectacular fashion as well. One PIece can do the same but many people would agree that Luffy's best moments passed ages ago.
Tearjerkers
Both shows are known for some pretty emotional moments but Fairy Tail can boast so many tearjerkers that it would empty a modest sized tissue box. I only remember crying once watching One Piece.
Comedy
Sometimes Fairy Tail's comedy moments can come at inappropriate times but the moments they get right are hilarious, One Piece has similar issues but current chapters seem to be taking away the humor.
Translations
Fairy Tail has a lot of translation issues early on, which is strange for a series not set in Japanese culture, many moments in the dub have made little to no sense whatsoever. 4Kids aside, One Piece rarely has issues with translation.
Story
Fairy Tail rarely keeps a story arc going for too long to avoid them outstaying their welcome and their cool down episodes contain some of the best comedy anime has to offer. One Piece goes on and on and on and on.
Dubbing
Fairy Tail boasts one of the best dubbing performances of all time with special mention to Cherami Leigh, Todd Haberkorn, Colleen Clinkenbeard and David Wald, honorable mentions to Patrick Seitz, Jad Saxton and Monica Rial. One Piece is just as good but is still haunted by the 4Kids dub.
So from that little analysis, Fairy Tail is a much stronger anime and able to out perform anything Shonen Jump can come up with. Yeah it still has the same weaknesses as other Shonen series but the stuff it does well is better than anything it's rivals can come up with.
Final Verdict: If Shonen Jump isn't satisfying your taste buds for action then Fairy Tail is the first choice anime for you.
