Most of the time having different runlevels available is not needed. They 
can come in handy at times though when they may not be as useful as they 
once were. In the case of RedHat, there is little distinction between 
runlevels 2 and 3. The default set up tends to start some daemons in level 
2 that should only be active in level 3.

In general, I only use run level 5. Occasionally, when updating the system 
(or X in particular), I need to switch to run level 3 (everything running 
except X) when something happens to X which prevents me from logging in or 
even having the X log in screen available. The number of run levels is 
probably more than is needed most of the time anyway these days. I can see 
run levels 1 (single user mode?), 2 (no network), 3 (network, but no X), 
and 5 (network, and X). I forget what level 4 was meant to be used for 
historically but  it is probably not needed in this day and age.

Run levels can be a help in administering a machine (particularly in cases 
when difficulties arise) but to the average user, they are probably irrelevant.
