I meant with better which kernel have the better lerformance regarding the Atmel SoCs.
Is the mainline kernel more reliable regarding Atmel SoCs ...
Using buzzwords for criteria is not sufficient. You have not specified any metrics.
The kernel configuration, the kernel version, and toolchain would probably have more impact on "lerformance
" [sic] than the location of the source code.
Reliablity can be a crapshoot if you happen to perform the git clone after a risky patch has been commited.

and it will take a while until the drivers from linux4sam will be merged in the mainline kernel.
In general that could be true.

Maybe you don't understand software development.
Microchip/Atmel needs a repository that they can control for development of their products without the delays and hassles of submitting patches to mainline.
There can also be more or alternate configurations (e.g. .dts
files for boards with various displays) that mainline will never accept.

Acme Systems sells boards. Why point its potential customers and users to another site where boards are also promoted?

Or which sources are the better or newer regarding Atmel SoCs?
You still haven't articulated any sensible criteria to make a reasonable choice.
I have already asked you two salient questions (regarding possible requirements) that could assist in a choice, but you have ignored them.
Besides, whatever you decide for a source, there will be someone else who will choose to use the other repository for their reasons.
I am just downloding the sources and building the kernel. Mybe I will make some own patches but only for my use.
For a build tool such as Buildroot, it's a simple matter of specifying the name/location of the github repository or tarball.
