Confuse!!!!

Does anyone know which one is better:1> Osi +9+7%amp+100hp(2slot)+206hp+92 def.-------Forcium +9+3% skill amp+50hp( one slot)+148 def+246 hp.---I'm confuse because obviously Forcium will give me more def 54 more compare with osi( hp won't count because they are pretty much the same.) However, osi give me 4% amp. So my question is when i pvp which one is better more 4% amp or 54 more def?


-In addition, how much attack i will receive more from 1% sword amp if my original attack is 1000 ?.
