Then i saw a local reef guru vacuuming and mentioning its very important. Do any of you folks with long term success with a reef vacuum ? Thoughts.

Vacuuming is for carpets. In a reef you want to cause all the bacteria and tiny critters to thrive so they can feed your coral and inverts. You do not want to remove them from a sand bed.

I haven't in 5 or so years that I've had a reef unless I was vacuuming up algae

I have a 1/2" to 1" sandbed that I vacuum every couple months when I do a water change. Over the years I've found that this helps get rid of a ton of debris and junk buildup. My sandbed stays "fluffier" and cleaner this way and I never have to worry about unleashing deadly stuff from the sand if i disturb it. I have earthworm like critters that get unearthed when I vacuum but I just let them blow around the tank until they settle and dig themselves back in. IME if your bed is shallow, there's more good to be done by vacuuming than bad. You don't need a sandbed to generate critters. Bare bottom tanks are proof of that.

You guys are in denial.

Vacuuming is one of the best weapons you have against old tank syndrome.

Critters are a waste of time. You want a clean tank that isn't incrementally becoming more and more sodden with waste and nutrients. No one sets out to spend thousands of $$$ on a life support system for bugs and beasties...
