The fact that it doesn't use the page cache is one of the top reasons why I love zfs - it can do a lot smarter decisions (MRU+LRU instead of just LRU) and integrate it with L2ARC.
Of course it depends a lot on your read/write patterns what impact this has, though.
On adding disks, I don't know if that's what you're referring to, but you can't add new disks to an existing RAIDZ.
Personally I've only used mirrors and single-device vdevs so far, haven't seen any need for RAIDZ.
