The wiki page says:

The 18.04 kernel delivers new features inherited from upstream, including:

• ...
• New default networking queue management algorithms to improve networking on slow and congested links

Do someone mean what do they mean exaclty?

I'm still seeing 4.15 on desktop and server, I guess one must explicitly ask apt for one of the 18 linux-image-5* options but which one?

IIRC HWE is enabled by default on 18.04.1+ , but if you initially installed 18.04 you must opt-in.

EDIT: See anarki2's link for how to enable it.

It is referring to the CAKE algorithm.

Thanks, odd that 0 of the LTS from kernel.org are supported by Ubuntu.

Not particularly surprising since both Ubuntu and RHEL maintain their own kernels with many additional patches which aren't official Linux kernels.

RHEL 6 - 2.6.32
RHEL 7 - 3.10
RHEL 8 - 4.18

Ubuntu 14.04 - 3.13 (3.16 3.19 4.2)
Ubuntu 16.04 - 4.4 (4.8 4.10 4.13)
Ubuntu 18.04 - 4.15 (4.18 5.0)

They support 4.4 with 16.04. It'll be supported for 4 years longer than the current 4.19 LTS release. Granted that those have passed their (Ubuntu's) extended support cutoff line (April '18) and are only receiving exploit fixes & critical updates anymore so that's kind of moot.

Their 4.15 team must be porting a lot of stuff from 4.14 or 4.19 or something...makes no sense to use it otherwise.

Looking at the release and EOL dates of the other LTS kernels, 4.19 should be called a semi-LTS kernel.
