It's always better to time stretch your video rather than the audio. If you are doing more than one camera you can sometimes use cuts between shots to compensate for the time differences, rather than stretching or compressing the video. Like it was said above, stretching or compressing (in the sense of time) the audio often results in a distorted sound.

I've stretched or compressed audio at least a thousand times while syncing in with video and never have had a problem.  Not to mention, when you're dealing with old analog sources, quite often the audio doesn't run at the correct speed.

If stretching a two hour audio recording a fraction of a second distorts it - you're likely doing something wrong within the software program.

In many cases you'd have to correct both time **and** pitch. Depending on the source material, one algorithm might work better or worse than the other.
E.g. I found Elastique Pro to work better on droney or psychedelic music than the built-in timestretching algorithm of my DAW.
