I haven't played all characters or paths on the console, but I'll give it a shot.
& Variants - Both paths are great. Sheep Burner is less situational, but does less damage than Blitz, whereas Blitz is more situational as the charge requires straight aim, but is just much more strong.
- Total Tongue is useless in PVP and mediocre in Story. Ultimate Spinner is strong but difficult to control. Ultimate Spinner is better overall, at least it's powerful...
- I haven't played both paths but Marauder is GODLY.
& Legendary - Granite Dragon gives insane power in both modes with a simple swipe doing 80 damage. I haven't played Pulver but it would probably be less useful.
- I've only played Crystaleer but it seems to be the right choice. I hardly ever use the lasers on their own.
- I haven't tried Earthen Avenger but Grand Boomerang Master is DEFINETLY S-Tier.
- Sandhog practically grants you perma-invincibility that also damages. Brawler is probably still solid though.
- Glacier Yeti is good for Story but useless in PVP. Blizzard Brawler is solid in both modes.
- Only tried Tesla Dragon and it's below average.
- Harpooner is poor because both Jetpack and Water Hose become useless while the harpoon itself does little damage. Water Weaver is infinitely better, being able to damage with all his attacks while being a fun and solid, highly underrated fighter.
- Haven't tried Commander Crab but Captain Crustacean is a solid and quick melee fighter.
- Didn't even CONSIDER Blademaster as I always saw Flame Soul as the premier attack...
- Blaze Dragon is mediocre in both modes.
- I went with Pyromancer only, but I'm guessing they'd be equal.
- Demolition Troll turns him into a great hurler.
- Master Blaster is boringly powerful. Broken. I want to switch to Clockwork.
& Legendary - Golden Frenzy is a bad version of Drobot. Golden Money Bags is a powerful glass canon.
- Bone Crafter is great in Story but mediocre in PVP. I haven't tried Shade Master.
- It's been settled that Nether Welder is better on PSC360 and Shadowdancer on Wii.
& Legendary - Both paths are awfully frail and weak. Vampiric Warrior, you may as well give him something that can damage at all.
- Skull Master is completely superior for PSC360 and both versions of Story, but Fear Eater is SO much better in PVP on Wii.
- Only tried Tempest.
- Medea. The roar is strong enough, and Siren doesn't give any good boosts in the PVP department.
- Eye of The Storm. No contest.
- I've only tried Lightning Lord. He has solid long range attacks down it.
- Vine Virtuoso is more balanced and powerful overall and gives him the long-range attack Melon Master lacks.
- Nut Crafter is the only one I've tried but at least he's not another Life melee down it.
- Haven't tried Artilleryman and I don't want to, Floral Defender is simply... Epic.
- I haven't tried Forest Ninja but down Pook Blade Saint she becomes the single most broken meleeist in the game.
