A7II? much worse than A7rII

Hi.

i had a dream. A dream about getting a a7rII. Since its a hobby im rethinking my decision because prices are not as my wife wishes

i have to upgrade (40D) to something. i tried the Olympus world with m43 but it was not the experience i wished. The a7 series feels awesome so i think i will go mirrorless and sony.

as the a7rII is very expensive in germany and i dont want to buy in UK im thinking about waiting or buying an a7II and one lens more or so. Or even the a6300. The only thing about the a6300 is the look of the camera and its not full frame... i know....

it would be nice to have a camera for my canada trip.

are there some things i should consider?
