I am currently trialling CP and although it does offer some things I like, as it stands I will stick with Aworka. I find Aworka simpler to use, although that may be because I used it first and find it more intuitive. The support for Aworka is satisfactory, but from what I have seen not a patch on CP's support.
CP offers features that Aworka doesn't currently offer though, notably texting and Gocardless support.
I have the feeling though that there won't be much further development from Aworka. It is a little slow at times too.
