You would want to go with the AS5400XM or the ISR. All other 5x00 platforms are going to run the legacy DSP hardware, Nextport DSPs. You will find much less support and features for these DSPs, and won't have as much feature support as something like that AS5400XM with the AS5X-FC card (PVDM2-64's).
And then, the only real difference between the 5400XM and ISR platform is horsepower. The support is a little bit different - 5400's don't support MGCP/media resources with CUCM, and a host of more specific corner cases that they do support. The VGD-1T3 is a good high-power box if you want to use it with CUCM, as it's based off the 5400 platform, and includes CUCM features like MGCP and transcoding/mtp/conferencing.
