-lowlatency == -generic + more aggressive low latency kernel configuration
It can offers all things that Ubuntu offer with -generic so -backport
modules, video closed drivers and so on. It is very solid and oriented
to "soft" users. Trade-off between low latency and power consumption.

-rt == -generic + plus PREEMPT_RT patchset (this is the realtime Linux)
It would want offer the same but require a lot of works. it would want
be aligned with -generic version but it can't be able. It isn't very
solid and it is oriented to "hard" users only. Power consumption is a
secondary concern.

-realtime == vanilla (kernel.org) + plus PREEMPT_RT patchset (this is
the realtime Linux)
It don't be interested neither to be aligned with -generic kernel nor
be compatible with all closed video rivers shipped (and worked) with
Ubuntu. It don't provide -backport drivers. it is very stable and it
is oriented to "hard" users only. Power consumption is a secondary
concern.

Ciao,
Alessio
