Your bounce should *never* clip if you want it to sound good everywhere.
Actually, some home/car hifi adds a little bit so it's best to peak at -0.3dB.
If you want your mix to *sound* hotter than that, you should add some
compression/limiting in the end signal.

Well you should avoid clipping more than compression. The few extra tenths of
dBs won't really make an audible difference (apart from the clipping). Some
mild compression (or even just a careful adlimiter just to shave off the
peaks) won't necessarily hurt. Note that clipping is a form of compression too
(the clipping sounds are exactly 0dB where they actually should have been louder).

I have all the recordings way below 0dB (that's what 24 bits are for). During
the mix, I try to keep all the individual tracks below 0dB, not that it
matters for the audio quality (floating point mixing means you can make levels
inside the mix as huge as you want as long as the output signal doesn't clip)
but it does help me keep the mix under control. The end signal is below 0dB,
and must always be. If there is only a single clip, I condsider it a failed mix.

Well then stay below 0dB, and preferably below -0.3dB. Compression is always
less bad than clipping. :)
