I'm actually a fan of all three devices that I own... Axe FX III, Helix (floor), and Kemper Stage (pedal).
Bass player is using my Kemper Stage live. I use the Helix for when I play church gigs and as a backup
for my band gigs.
Axe FX III is the king for me and is of course currently the number one gig device. Just not worth
me carrying a rack and a pedal in for the church rock band gigs.
I rank them
1. Axe FX III
2. Helix
3. (close 3rd, maybe a tie) Kemper Stage
If I could choose to have only one, Axe FX III hands down.
I could, however, live with any of the three music makers if they were the only thing available....
