Did you bother reading the third link? That offers the direct comparison.
"There's the GT-I9500, which has the Samsung Exynos 5 Octa running at 1.6GHz, but no LTE/4G modem.
There's the GT-I9505 (the model in Australia), which has the Qualcomm Snapdragon 600 running at 1.9GHz and an LTE/4G modem."
If you need LTE/4G capability you go with the second one. Better battery go with the first one.
Sorry man i am not that good in english
I want bigger battery and better gaming performance . i don't want 4G in my phone . it is all about the device performance
so i suppose the I9500 is better in performance
