I tend to select things based on if Lapua offers brass for it so for me it'd be 22-250 or 22-243. If you are going to use a fast twist long barrel, maybe look into 22-284 but you really need to shoot the heaviest for caliber bullets and use a relatively long barrel to see the benefit.
I'm a bigger fan of hot rod 243/6mm stuff because I think it offers more versatility. If I wanted to shoot lighter bullets super fast I'd go with a 20-250 or 20-250 improved and shoot the 40-55 grainers.
But, if a hot rod 22 is just what you want, in all honesty, any of them you've mentioned will get it done. How much you're willing to spend and how much prep work you want to do will help determine which reamer you have your gunsmith stick in the barrel.
