Hi JayFreddy!
How do they do different things?
All I want to do is get from point A to Point B

Why would you get both a big board of individual pedals and an expensive MFX designed specifically to replace that pedalboad, and what do they do differently? Why is it a false dichotomy? What would I do with one that I wouldn't do with the other?
Sometimes I go into the woods to breathe clean air and refresh my spirit.
Sometimes I go into the woods to go fishing.
I don't hunt anymore, but there was a time when I did, and I brought tools specific to the task.
It is possible to think of individual pedals and multiFX as equivalent ways to achieve the same goals, and sometimes that might be true.
A Strat through a Marshall with a Wah and a Tube Screamer has a visceral feel that is about more than just tone.
I like the way that feels... It's inspiring.
But I'm not bringing a Marshall stack to a GB gig.
I currently own a boss ME-5, GT8, ME-25, ME-70, and an ME-80. I had a GT10 and a GT6, but sold those.
I have lots of amps too.
I also have nearly 300 individual stomp boxes that I have collected in the 40+ years that I have been collecting them.
I enjoy my toys.
One can get from A to B lots of different ways, but to me, there's a point where it's less about where I am going than how I get there.
I used the term "false dichotomy" not as a diss, but simply to point out that it's not a black or white proposition.
Harley or Toyota? They will both get you from point A to B.
But they aren't "the same".
The Harley is cooler, but sometimes the Toyota is still the best choice.
Ps. I usually tell my students to start with a multiFX. More bang for the buck and it's a good way to learn. But that doesn't mean that they're "better".
