How good is the W-VHS analog format And should I use Digital-S (D-9) tapes instead?

I read Digital-S (D-9) tapes over W-VHS tapes are preferable as their runtime is higher but I would also like to know other aspects. For example I heard they can record in 480i and 1080i resolutions... does that mean W-VHS or Digital-S (D-9) tapes can equal or even surpass DVD quality? In terms of price I would image DVD is the way to go but I just bought a AG-1980 to transfer all my tapes without jitter and I noticed it can record in W-VHS so is that better then record directly on my PC with a card like PCTV for example?
