Is it better to us emerge -U or emerge -N
I've always done -N but it didn't go very smoothly it seems to me -U
might be better option but it takes longer.
Right now I'm doing -U and it is compiling 549-packages.
.
I always do both except I use the lower case 'u'. I started using
Gentoo back in 2003. Over the years, I added/changed options to emerge
until I got a good sane system that works as expected and is stable. My
command is emerge -auDN world and it has worked for years. One
difference, I update once a week and on occasion two weeks if I have
something going on and need to wait. I'd think tho, if one goes a long
time between updates, my way would result in a longer compile time but
also a system that is more stable or clean.
Everyone has their own way. If what a person does is working, by all
means do it that way. I picked my way because of problems I ran into.
The solutions to those problems resulted in the command I use. If one
waits a long time between updates, more packages will have updated and
result in more updates regardless of the options. In that case, any USE
changes would apply to those packages anyway. If one updates often, as
I do, then the way I do it may have benefits and result in a more stable
system, even tho it requires more packages to compile.
Hope that helps.

I've asked ChatGPT for explanation and here is what I got:
Here are the differences between emerge -U and emerge -N:
emerge -U: This option upgrades the specified package(s) to the latest
available version. It will first download the new version, then build and
install it. If a dependency of the package being upgraded also needs to be
upgraded, it will also be upgraded.
emerge -N: This option installs the specified package(s) without upgrading any
dependencies. It will only download and install the package(s) if they are not
already installed. If any dependencies of the package(s) are not already
installed, the command will fail.
In other words, emerge -U upgrades packages and their dependencies, while
emerge -N only installs packages without upgrading any dependencies.
