JSB PelletsDiablo VS FX or Daystate

I usually buy a ten pack of pellets when I get down to a couple three tins left. After I see what my gun shoots I stick with that pellet. I have seen the 10.3 JSB heavy I am looking for hasn't been available. I notice a few dealers have what they tell me is the same pellet in FX of Daystate. My question is this. Does a JSB FX or Daystate 10.3 diablo shoot consistently the same as in if you just have a different lot # I am not actually asking for the best just do they compare closely between these brands?
 
I just got a tin of .22 - 18.1/3 FX Diablos in. I loaded and fired 10 quick rounds through my Steyr Pro X. Two things I noticed 1) the FX seem to be a much tighter skirt fit in the magazine. 2) all ten shots stacked as well if not better than my JSB’s. Of course not same caliber and a very quick test of functionality but I’m pleased.
 
My order of 10.3 JSB pellets will be here Monday, I jumped the gun and ordered 4 tins of the 10.65 baracuda H&N in hopes they shoot as good as JSBs do,,, Now I have a few tins of the 10.3 FX pellets For some reason the FX shoot higher about an inch and have a lot more flyers than the JSB pellets, But the FX can is pretty,
