Maybe an answer from a noob user could be of interest here.
Context: started with fuerte, wrote some simple nodes, recently tried moving on to groovy.
The whole catkin thing was a huge blow after the already inexplicable roscreatepkg+rosmake.
I still don't understand why do I have to learn another series of build tools when there is cmake+make.
On fuerte I ended up using cmake most of the times (after one pass of rosmake to generate msgs or services) as I could not get rosmake to update the makefiles if I changed the configuration.
Now with groovy I totally don't get the workspace thing and the new command.
Plus at least there are rosmake examples out there, while catkin ones are difficult to come by.
And on top of this all, I can't see how to integrate catkin in IDEs which to me is a must if you really want to code for ROS.
Now this is the perspective of a programmer just approaching ROS, not criticizing anyone. But I want to stress that, not being part of the inner circle, some things appear strange and unmotivated (new wheels every time).
Best regards
