Unfortunately, there's no single setting that is "best". What looks best is highly dependant on the source material.
Bob just throws away half the frames and thus half the resolution so try to avoid Bob unless you just don't have enough CPU to do anything else. Or if the source material is causing problems for all the other deinterlacing schemes.
Blend, Mean and Linear all use various filters that will soften the picture a bit but should retain more detail than Bob. Depending on the source material, one might look better than the others.
I can't recall what "X" does.
YADIF and YADIF 2x use extremely complicated prediction algorithms. If you have enough CPU, YADIF will usually give the best results with the most detail. However, on some material, YADIF causes ghosting (double images). YADIF 2x is an attempt to eliminate the ghosting but takes even more CPU and doesn't always succeed in eliminating the ghosting.
If you have enough CPU, I'd suggest defaulting to YADIF and switch to something else only on material where you see ghosting or other artifacts.
In the attached thumbnail, you can see the controls for changing the default deinterlacing settings.
