I have an AxeFx Ultra but I am on an extended work assignment away from my actual home. Rather than take my AxeFx rig, I took my trusty Pod XT. I just pulled the trigger on a bean HD to replace it so I can try out Line 6's new tech (they added the Soldano model so I didn't have to break my solemn vow to never buy a modeler that did not model the SLO). I adored the XT, so I am sure I'm in for a treat. Even though I have a "bigger" rig, I found lots of uses for the XT due to its portability, ruggedness, and inexpensive (compared to the Fractal) replacement/repair cost, I've used it as a preamp/FX unit for a combo amp via the loop, a dedicated sound card for my laptop (Axe was interfaced to the desktop system), etc.

PODs are incredibly useful tools, I sold a ton of preamps, pedals, amps, and other rack units whne I got the Axe but kept the XT, one combo amp, one rack unit, and two stompboxes. To me being on that short list says a lot for those units. I fully expect the HD to be a worthy replacement.
