I love my GrillGrates, just don't like the gasser they are on. That being said they work well on either side and for all kinds of things. My wife likes them when she makes carne asada. As for the not flat side, I take the example of Meathead and throw out some pellets in the grooves. I've never used the Vortex but i would imagine it is pretty much like searing directly over the chimney. $0.02
A couple of years ago GrillGrates had some overstock and put some of their standard plates on clearance. I was able to pick up four plates for less than $100. Trimmed about ¾" off one plate and turned my dad's base level CharBroil into a nice little cooker.
Here we have 3 Medium Wells, 6 Mediums, and 3 Medium Rares.
I agree with:
But, as they say in BBQ & Grilling, YOU cook your food the way YOU like it cooked and never mind what anyone else says. SJ
Reverse Sear, Sear-n- Slide, Sous Vide, Vortex, GrillGrates, Slow 'n Sear, Flattop, Grill Marks, etc., etc., etc.,
Lots and lots and lots of choices. Pick the one(s) that work(s) for you ! ! !
