Which of these 3 phones should I purchase?

Hi all,

As described in the title, i'm in doubt about which of these three phones i should choose:
-Wiko Wax
-(Huawei) Honor Holly
-Huawei G620s
They're all in the same price range in my country, and they don't differ very much i believe.
The thing is, with phones i don't really know what really makes a difference in performance and what is important.
The wiko has more gpu cores and significant higher clock speeds regarding cpu, ram, and gpu, but i don't know whether this makes a difference since it's another brand of chip.
You can't compare amd vs intel with same clockspeeds so i guess it's the same with phones.
The holly has 16gb of storage while the g620 has 8, the wiko has only 4gb.
A good custom rom would be nice, and i think there are more and better roms for the huawei's
However the biggest point of doubt is the durability of the phones, which one is the most rigid.
So which of these phones do you think i should buy? Also, if you think there's a way better phone than these ones in the same price range feel free to recommend it.
Btw, in holland where i live most cheap chinese phones like doogee are unfortunately not available.
Thanks for your time! :)
