agreed with super
UA pros: better land scape more boss's like Mihawk and Crocidile and CP9 and Shanks AND WHITE BEARD WITH HIS INFAMOUSE 1 HIT KILL xD the rewards for defeating boss's where alot better and u didn't have 2 start from begining on new game+ u could run up and fight white beard striaght away

UA Cons: farming for items was worst i mean u could watch a film and pressd the button every 20mins coz fruits would rs but that was making the time dragg. No team moves. farming Gold Whales and Gold beattles was pure boring as the whale would escape with in 2secs on getting caught and the beatle gl finding 1 max HP n SP was 2000 -_- thats alot off golden dishes

UC1 Pros: TEAM MOVES. support moves. brooke diff moves from the moria arc. less to make and easy 2 max ya stats. diff bad guys and u can fight Kuro, kuma, black beard, moria, BUGGY <3, nightmear luffy. and with this game u dont have 2 max waste time level ya stats on the 2nd one as u start with them at level 8 <3 and Oz is in that 1 :p
u get 2 play on merry :D the whateva cannon and the sligshots back fast movement arnd maps

UC1 Cons:the fishing rod u need 2 upgrade like 30times -_- DONT USE YA PIO on pnts save them or at least 10. converting points is abit off a dragg as most off the ops require gold and only a few things add to that :\ best way is farming tresure prangi as u only need 18 off them 2 begin with

hope this helps
