Got to agree with @BigRedX, and say that you need to work on a sound that works for you and/or the band/musical project. Try and approach building a new sound as if you've just got a new rig. Find an amp/cab sound you're happy with, tweak it till sounds how you want it, then start adding effects. If your core sound isn't right, then you're not going to be happy until it does. Adding some IR's might help getting the sounds you're after. Bought some Celestion IR's, and they've made a massive difference.

The Years Without Light - GWAR

Mr Blue Sky - Electric Light Orchestra

You Spin Me Round - Dead or Alive

I'm making the assumption that the rest of the band are feeling the same way about the situation? If you haven't discussed it together, it's time to have a band meeting. If they feel the same way, then sack the current singer. If they don't feel the same, then walk away. Or stick around and pander to the singer...

Stairway to Heaven - Led Zeppelin

Have a one off HW 4003, superb bass.

Breadfan - Budgie

Simultaneously too many and not enough.

Call Me Maybe - Carly Rae Jepson

I'm the Urban Spaceman - The Bonzo Dog Doo Dah Band

I used a Line6 HD500x before the POD Go, but had got to a point where I was considering individual pedals, or the POD Go (went through the same process going from the PODxt Live to the HD500x). Costed up choice pedals, tuner, a PSU, a board/case, patch cables, etc. and came to the conclusion that the multi-FX was the way to go for me. If you factor in that if you bought say 6 pedals, you may need to replace 2-3 because the original choices may not work out for you and be replaced. GAS plays a role too.

I suppose the next question would be, do you need amp/cab modelling, or just effects? If you're just wanting effects into your amp, then it would be the HX FX every time. If you do want amp/cab modelling, then you need to ask yourself more questions. How many effects do you need at one time? More than 3 per song, then the POD Go is out (have one myself, it's great, but limited). There are work-arounds, likes switching between patches/presets. The HX Stomp / Stomp XL have most of the functionality of the Helix, but not the footswitches or connectivity. Loads of options though, parallel signal paths and lots of other goodies. Sure a HX/Helix user will be along to fill in the plus points. Don't know much about the B6, but it'll have plenty of effects as well as amp/cab models, so loads to choose from. Having been down the pedal board rabbit hole with guitar effects, it is a hit or miss affair, which can end up with serious serial pedal purchasing just trying to find the right pedals that work for you. Great fun, but a complete money pit, and you end up with a ton of pedals, associated boxes and other paraphernalia kicking about.

Two Minutes to Midnight - Iron Maiden

Bought a lot of stuff from Thomann pre-Brexit, no issues at all, and always cheaper than buying from the UK (especially when it comes to postage costs).

Rock and Roll Aint Noise Pollution - AC/DC

Red Barchetta - Rush

Are You Gonna Go My Way - Lenny Kravitz

Get Up, Stand Up - Bob Marley & The Wailers

Those "cat eye" soundholes are cool. A lovely looking instrument.
