Orgalmer - Nice recordings. I correctly identified which was which before realising you had written it up. Out of the sub and the normal I prefer the sub. I am a sub tuner myself too. I find it just opens up this real nice growly tone in the low mids, and also leaves a space which is more useful for the guitars. The downside is it can get a bit quiet (especially on a sub-par listening system). It is a very nice sound though and I much prefer it to the regular a lot of the time. The octaved one sounds real good and makes up for the lack of perceived volume. I'd be interested to hear a direct comparison between sub tuned and pitch shifted, without the original higher octave there. To see if that improves upon the issues of thick strings and their darker tone etc.
