Having couple of limit= lines is quite limiting ;) The channel groups is 
the most flexible solution, but not the most easy for set-up. It takes a 
little overhead to write another layer of "numbers" that match to 
physical SIP devices, and behave you need. As I've heard before - 
Asterisk is a hacker's tool that would allow nearly unlimited 
possibilities if you know how to configure it. Disadvantage - you need 
some logical and programming skills to do the hardest tricks.

As for channel groups - i currently have only one wish - to be able to 
limit based on channel group in queue. However that might increase 
complexity of settings - being able to do that on dialplan is the most 
easiest way.
