Well, there's basically no similarity.  They're both alternatives to sending 
your password to a server, and the similarity ends there.

In CBcrypt, the servername, username, and password are all combined to create a 
site-specific, user-specific, password-specific keypair, a keypair that is 
deterministically recreatable by anyone who can combine those ingredients 
together (which requires knowing your password.)  Only the username and public 
component are sent to the server.  There is no need for any keychain manager or 
clientside app, as this can all be done in javascript, java, .NET, or whatever. 
 The only thing a user needs to carry with them is knowledge of their own 
secret password, which is never disclosed to anyone, but *is* securely 
verifiable nonetheless.

If SQRL is going to take off, it sounds cool.  But it requires a client-side 
application performing the task of keychain management, and if a user travels 
from device to device, they must synchronize their devices together somehow.  
There are a bunch of people writing articles about problems with SQRL on the 
internet, but that doesn't necessarily mean it's a bad thing.  I think most, if 
not all, of its problems can be solved except for the necessity to carry 
something with you and synchronize it with yourself at other devices.
