Just discovered two things:
Changing EPSG to 3857 makes the TMS compatible with Openlayers plugin, 
looking much better. 900913 and 3857 should be principally the same, but 
Qgis makes some reprojection which makes the TMS tiles rather weired in 
3857 projects.

And with TMS I can use self-made transparent overlay tiles, setting the 
transparency color manually to RGB 0-0-0. Thats the only thing I can not 
do with Openlayers plugin at the moment.

HTH,
