Well, it still boils down to
(a) whether your source footage is Hi Def or not (if it is you'll need premium OR some otherway of down-converting your footage to a format VMS8 will undertsand)
(b) whether you want to use the excellent primary colour corrector (although the same can be achieved with a lot of hard work using levels etc - or so I believe)
(c) whether the New Blue effects are likely to be of use to you.
(d) whether you want to use Dolby (ac3) files - which you won't for the web so ignore (d)

The ability to output a format suitable for the web is IDENTICAL in both versions.
