All depends on your defintion of "best".

Some shooters want to pay less to define "best"
Some shooters want less fouling to define "best"
Some shooters want longer spells between gun cleanings to define "best"
Some shooters want whichever's more accurate to define 'best"
Some shooters don't crud rings defined as'best"
Some shooters don't want patch or plastic sabot deterioration to define "best"
Some shooters dont want breechplug seizures to define 'best'.

There's more....... it's reallywhat you want/think - not what werecommend, Both have equal power/energy per the same amount of grains. You make the call.
