Your signature lists a Kemper, which should cover the waterfront so I'm a little confused by the question... maybe that just lives at a studio & doesn't get taken out to gigs? Multi-FX units are a great thing to have for any cover band performing live with a wide range of styles. There's a dizzying array of options for every budget - other end of the spectrum from Kemper has improved a lot in recent years, all the way down to a lowly $100 Zoom stomp box to tack onto existing pedal board. Lower end ones will never compare with with $2K modelers, but can still be pretty good live if you invest the time to learn & program whatever you get, and tweak to the rest of your rig.
I love my HX Effects personally as great bang for the buck & particularly find its switching/MIDI capability useful, the firmware updates for all the Helix stuff keep adding new effects every 3-6 months. It doesn't have a lot of really "out there" sounds like horns or robust options for synth tones (3.15 firmware added a few that I haven't explored), it's harmonizer isn't as good as a Pog or an H9, but they did add polyphonic harmonizer settings. HX Stomp is more compact if you don't need the extra connectivity/MIDI of the HX FX.
