I seem to have issues getting natural sounding feedback from the freqout, especially when you hold notes (Gary Moore or Santana), it doesn’t take to the vibrato quite well. Also there is the issue of feedback dying out abruptly.The digitech freqout seems to be great . First time I ve heard it as I’m not really interested by a feedbacker, but yeah that’s cool finally
I dude of mine said, he doesn't like modelers because of missing feedback. This could be an additional key for success.

At the risk of being drawn and quartered, I do think about picking up a Helix Stomp from time to time to run in a loop and use some of the effects that Axe FX doesn't do well/at all. This and the glitch delays come to mind immediately.
Could be a nice supplement to the Fractal Universe.
