So let's start with this. I went deep down the rabbit hole on all of this a few years ago. I wanted to become the steak guy with all of my friends. We had brisket guys and rib guys and crawfish boil guys. So I went all in on steak.
When we say A5. The A is irrelevant to us, it's just the yield of beef compared to the weight of the carcass. The 5 is what matters. It is the marbling score the scale of marbling is 1-12. Anything with 5-7 marbling gets a "4" and 8-12 gets a "5". So within "A5" wagyu, there's a pretty big range.
Next, what matters more than anything is the species/region of the cattle. I probably bought wagyu from a half dozen or more butchers in the Dallas area. There was always a big range of quality, but I do remember most of the wagyu coming from South Texas and I got one steak from a Colorado ranch at my butcher and it was noticeably better.
Fast forward to today. Mountain/Northern cattle are amazing compared to the crackhead cattle I saw all around TX. These 17ers are huge up here. Cool summers let them fatten up for cold winters I guess.
So with all that said, the best wagyu you will buy is Snake River Farms gold grade. It's American wagyu (which everything else you get your hands on will likely be) which is better. The founder of SRF basically started wagyu in the US and brought over a dozen or so bulls before Japan banned the export if the bulls.
SRF bred the Japanese cattle with Angus and has mastered it. Wolfgang Puck says it's better than Japanese wagyu because you get the Japanese marbling and the string beef flavor from the Angus.
The gold grade has a marbling score minimum of 9. So it's going to be as good or possibly higher than "A5." And after having it all the time now, there is no going back.
With that said, I am lucky in that it's available in the grocery store here. I will post some photos later of some of these bad boys I have cooked.
So my suggestion is find what you want from SRF's website and use that as your starting point. If you're butcher can get you A5 significantly cheaper from CO, WY, MT, ID, and WA... Go go for it. But if you are dead set on the best, SRF is it.
For cooking, I have a Kamado Joe and don't use it for steak. I either go cast iron skillet to sear and finish in oven or use my inferno steak cooker.

Cool video CBS did on SRF. Good info on wagyu.

Here's a less than $10 per lbs SRF wagyu petite steak I picked up a few months back... Delicious.

This is what I cook my steak on now, an Inferno overfired broiler. 1500+° 1.5-1.75 minutes per side for a 1.25" steak.
