Ah, I assumed the default to be at the 4.9-2.3.x-imx branch. That one is 
based upon 4.9.166, which is much more close to the latest upstream.

A recent kernel from a longterm branch is probable the best to have. 
However, I feel that it is mostly important later in the development. 
Starting with defaults usually gets you going without too much hassle.

For small, short-lived projects, starting with any LTS kernel is fine as 
long as you get to a recent one before release. With larger and 
long-living developments, you have to cater for major kernel version 
jumps anyway.
