I was at a buddy's downtown apartment a few weeks ago and had some monsters to cook (2 inch thick bone in ribeyes). I cooked them reverse sear, they came out perfect.
Not as good as Sous Vide then sear, but good enough for Government work.

I always reverse sear on the grill now. Best steaks I've ever done.
Kosher salt 1 hour ahead of cooking, rest them on the counter. Fresh ground pepper before putting them on, and as long as it's a thick steak, a light dusting of garlic powder and onion powder, and sometimes a very light dusting of chipotle powder.
On the indirect side first with top down, and I go a little cooler and slower on that side if time allows. I usually throw a few wood chips in on this part to just give it a little more smoky/grilled taste, but I'm not trying to really smoke it or flavor it that much. I like mine to get some pretty good charring on the sear, so I'll put it over the coals about 15 or even 20 degrees before my target so I can really burn it without cooking it too much. For normal people more like 10 degrees under.
It's the best and most consistent process I've ever had for steaks. I always grilled them pretty good, but 1-2 out of ten I'd miss the mark of what I was looking for, which was always disappointing, and even with most of them being wins, still some were great and some were just good. This way I hit a 9.5+ out of 10 steak to my taste pretty much every single time.
I do think a lot of reverse sear instructions undersell how much below your target temperature you might need to start the sear. Depending on your surface, the heat of it, and how much of a sear you like, it can cook significantly. Having a thick steak makes a huge difference. When I was sous viding, I always struggled with that...it allows you to take it to a perfect temperature, but it's very easy to cook it a level more in the sear process. No different with this...you have to definitely get a feel for when to start searing. I don't sous vide anymore, as I don't taste the improvement vis a vis the inconvenience, but the principles around that helped me a lot.
