I have accounts on both hushmail and ziplip, and find ziplip to be more reliable.  
If you're really paranoid hushmail might be a bit more secure.

Have 50 MB acct with Safe-mail, and a backup
35 MB with Ziplip. Good for sending large files and family pics.
Safe-mail is switching servers this weekend and still down.
It is all offshore. When you sign off, your data is all offshore and doubly backed up.
Ziplip is good and secure but domestic, in Mountain View.
Hush and Hot IMHO are a total pain.
Would not use Hush or Hot if paid to do so.
I am a heavy user of e-mail and need both storage and high security for clients. Also on the paranoid side.
Speed conscious. Hush is snail-like.

Hushmail is more secure, but it is somewhat  unreliable and it used to be a pain to go to a link embedded in a message.

Safe-mail is not really safe, the IP address of the sender is embedded in the header.

I use Ziplip a lot - it is fairly reliable, and I like the fact that you can send a messaged to anyone securely, and delete it from their mailbox if it is particularly sensitive.
