Going for the 4.14 kernel is absolutely a better choice. The i686 plus
kernel is just lucky to be existing. It would not have been possible
to maintain it without great support from people like Pablo and @kabe.
We initially got the 32-bit version from Springdale (formerly Puias).
Then they stopped building at some point. Building it becomes harder
and harder with each release, it seems. So, there is no guarantee that
there is another update to the i686 plus kernel.
