I'd have to agree here. Although FreeBSD's ZFS support is getting quite good now. I'm using it on a production system and it hasn't let me down. It even saved my bacon a couple of times (yay, ZFS snapshots).
I guess it depends on what you want to do. Both have strong features. OpenSolaris has Crossbow, but FreeBSD will have vimage soon. Both have Dtrace and ZFS. Solaris has zones, FreeBSD has jails. But I think FreeBSD is easier to tinker around with (personal opinion).
