How will the US version of the Google Pixel perform in Germany? I am a very happy Nexus 5 owner in general. However, I have noticed that my (US version) Nexus 5 does not offer LTE in Germany --- at least on Tchibo as a carrier, who resells o2 (and maybe E-Plus, I am not sure). Now I am wondering whether the (unlocked) US version of the Google Pixel will have the same problem.

GSM arena has some specs for the supported bands:

Yet I feel unable to judge the significance of the differences, especially in terms of which bands carriers may be deciding to use in the future.
As far as I know EU carriers use Band 20 and Band 3/7 in conjunction, one to cover the densely populated areas and another to cover the rural places. This Wikipedia page mostly supports my knowledge. Since the US variant has 3+7+20, it should work alright.

P.S. Are you buying from US to avoid the huge price bump in buying the global variant outright?
