Good question.
VDPAU internal deinterlacing is state of the art. It is a temporal / spatial algorithm, which uses more than one frame to calculate a smooth, sharp image.
XVBA also does internal deinterlacing, but without any interaction by us. The way they are doing it is at the quality of BOB which looks compared to the nvidia version improvable.
So to conclude:
1080i will work fine deinterlaced on XVBA, but the quality is the same as within ION-1 + BOB deinterlacing.
Btw:
Fernetmenta is working on a new vdpau architecture which should allow ION-1 with the advanced internal ion deinterlacing. There are already some testimages for openelec available.
