I went from 38cm road bars to 44cm 12deg flare Easton gravel bars. They both work. The wider option is almost certainly better for actual gravel riding. I don't feel any disadvantage on the road. The flared drops still feel weird to me and I don't use them so much (but also, who's riding around on the drops most of the time except people with a bad bike fit or whatever).
I have these. I'm basically in the drops on even-the-slightest downhill - feels very safe n comfy. Easton foam bar tape is very comfy/squishy too. Recommended.
Yeah, maybe going downhill off-road, but on-road it still feels odd. The deeper GRX hoods make it nicer descending or riding rough stuff and staying on the hoods.
