iPhone 6 vs Samsung S5

I'm having such a hard time deciding which phone to buy, my phone subscription is running out and up I'm for a renewal. I'm thinking of either a iPhone 6 or a Samsung S5 but at the same time, Samsung might be realeasing the S6 around the end of February or Mars. Or I'll keep the subscription and don't change my phone. Which means I pay less every month.

Such a first world problem haha 😂😭
