VueScan and SilverFast are the two leading multi-vendor scanner programs. Some differences are:
Universal Binary - VueScan runs faster on Intel Macs because it is a universal binary. Silverfast is an older PowerPC program that runs slower on Intel Macs (it has a universal binary launcher, but the SilverFast plugin is PowerPC only).
Multi-processor - VueScan runs faster on multi-processor systems (including multi-core systems) on Windows, Mac OS X and Linux. Silverfast doesn't have multi-processor support and is slower.
Number of scanners - a single copy of VueScan can work with all supported scanners, but you need to purchase and install a separate copy of SilverFast for each scanner you use.
Cost - VueScan Standard Edition costs $39.95 and Professional Edition costs $79.95. SilverFast SE costs $39.95 and SilverFast Ai costs up to $424.
Upgrades - VueScan Standard Edition includes one year of free upgrades and VueScan Professional Edition includes unlimited free upgrades. SilverFast upgrades can cost up to $304.
Film scanning - VueScan is widely acknowledged to produce superior scans of color negative film.
Infrared cleaning - VueScan supports on all scanners with an infrared lamp, SilverFast doesn't support on any Canon scanners and on some Epson scanners.
2 GByte scans - VueScan can do high-resolution scans that produce more than 2 GBytes of scan data, SilverFast can't. This is useful when scanning 4x5 or 8x10 film.
Ease of use - VueScan has a simpler, more consistent user interface than SilverFast, and is easier to learn, easier to use, and more productive for batch scanning.
