Mixing Midi VS Mixing Audio (sound quality)

So I get that Pro Tools is more versatile with audio, or however you want to look at it. My question isn't about capability though, my question is about the end result bounced audio quality.



I prefer to keep my tracks in MIDI so I can go back and change something if I want without having to re print. So if it makes no difference I would rather skip printing to audio pre mix and just going right into mixing my midi files. Only thing I'm wondering about is how is the actual audio quality of midi signalled audio vs printed audio? It isn't enough for me to hear a difference, but if there is a difference obviously every little bit matters.



So my question is, does the sound output from an audio track contain better quality than the sound output from an identical Midi track? Or am I clear to go on with EQing/compressing/effects on my midi track and just skip the whole making audio stems part? I don't want to if end quality will be sacrificed, but it will definitely be nice if it isn't.



Don't worry about CPU use, if that becomes a problem ill print to audio. But I'm talking about a scenario strictly based on quality of audio.
