Well... the ATAs are very old hardware now, and they aren't great. They have basic fax support (pass through only) and typically you get low rate connections. They run a non-standard OS, and have a very non-standard config interface.
The VG2xx are all IOS based, new hardware, better fax support for more protocols, and I expect they have a much longer future in terms of support/software maintenance etc.

I can tell you that on my lab 7.x system DLUs aren't enforced for the 202/204 (even in SCCP mode), although they are for ATAs.
