Hitting the limiter wont really hurt as long as you dont just RAIL on it at the limiter, if you just bump it by running a gear out too far it wont hurt but if you stand on the limiter all the time it will definitely do some damage. My old Talon had a pretty nasty setup on it and I would bump the limiter at 8200 all the time trying to inch people out at the end of a gear. I would also use the Two-step at 5800 with anti-lag with no ill effects, motor started with 180psi compression with 1000miles on it and ended with 180psi compression with over 20k miles on it. This was a spark-cut limiter which has been discussed above.
How bad is it to hit the rev. limiter?

There is nothing particularly wrong with a fuel cut rev limiter. A lean condition is bad, but a fuel cut rev limiter causes a NO fuel condition. That means no combustion, no lean condition... Just inert air in the cylinder. So no problem at all.
However, you don't want to hit a fuel cut rev limiter while spraying a wet shot or using meth/alky injection. In those situations, you still have fuel flowing from sources which the computer can not control and turn off.
And as others said, those 4 bangers you see at the track use a 2 step rev limiter. Setting the engine speed to around where boost comes in can allow you to launch with boost instead of waiting on the turbo to spool. I probably need one for my 2.3.
If not running nitrous or meth injection, I would rather have a fuel cut than a spark cut. In a spark cut, you still have fuel flowing, and raw fuel flowing through the exhaust. This could either cause a bad backfire, or rediculous EGT temperatures due to the fuel burning in the exhaust.
