I use stock for most installs, always latest patch level.
Exception is an ASUS laptop that I occasionally use an ELRepo kernel on 
to test out the various function key support, I have a number of 
backported drivers from these later kernels to enable the backlit 
keyboard etc on the stock kernels - with the kabi (?) kernel tracking, 
once these drivers are created they then work with the stock kernel + 
patched updates i.e. 6.3 to 6.4.
