This wikipedia article on clusters has some information towards the end.
The major differences between the two are that Sun Cluster is very tightly coupled with Solaris, while VCS is not. In the same vein, Sun Cluster works at kernel-level while having a few user-level processes, while VCS works exclusively at user-level (no kernel-level integration with any of the OSes).
The drawback with Sun Cluster is that it is available only on Solaris systems, while VCS runs on multiple OSes. This might be a factor if you have multiple unix systems (HP-UX, AIX, etc) and want to have a single clustering solution.

NAME
clprivnet - SUNW,clprivnet Sun Cluster private network driver SYNOPSIS
/dev/clprivnet DESCRIPTION
Note - Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor- mation about the object-oriented command set, see the Intro(1CL) man page. The SUNW,clprivnet Sun Cluster private network driver is a STREAMS pseudo driver supporting Sun Cluster resident applications that use standard Solaris interfaces to communicate over the Sun Cluster private network. By striping data traffic over all links, this driver opti- mally utilizes the bandwidth of the private network while supporting highly available, software fault-tolerant communication. APPLICATION PROGRAMMING INTERFACE
The driver is supported by the character-special device /dev/clprivnet, but is reserved for Sun Cluster internal operation and the standard Solaris network utilities. This interface must not be directly used for general application communication. ADMINISTRATION
The administration and configuration of the driver as a network interface is done completely by the Sun Cluster infrastructure internals. FILES
