Default Octa Core 3G vs Quad Core 4g AGAIN??

I am looking at buying this but i am now once again confused which one, the cheaper one to get is the octa core , but 4G is becoming VERY hard to turn down now... So i think its going to be the quad.

I am from Australia the standard is the 4G Quad.

Whats your thoughts and howcome there is not a thread for both phones like last year
IPhone 3GS >> Iphone 4 >> Samsung GS3 I9300 >> Samsung GS3 I9305 LTE >> Samsung GS4 I9505 LTE

Spec daily run :
Galaxy S4
2gb Ram
LTE (4G)
Snapdragon 600
QuadBEAST @ 1998mhz x 4
Andreno 320

Best Quadrant Benchmark To-Date = 15,255k @ 2.16Ghz
Best Antutu = 31,385 @ 1998mhz
