Vuescan vs Silverfast - Opinions

I just snagged a nice Nikon Coolscan IV from the Oxfam online shop and, of course my shiny new laptop won't run the venerable Nikon Scan 4 software Which I used back in the day. there are two what I will laughingly call the modern alternatives, Siverfast and VueScan. From a brief play bath are arcane, obtuse and old fashioned, but one must be the better bet, right? So does anyone in the EPZ world have a view.
