Compared to Linux and FreeBSD? Not a chance, Solaris was running circles around them in the 1990s when Linux was still a toy operating system and FreeBSD was figuring out their infrastructure.
These days, FreeBSD has adopted nearly all of the cool technical advantages Solaris has, and Linux seems to be actively hostile to adopting such things (ZFS, DTrace, ACLs...).
