Comparison of sniper rifles and machine-guns

I intresting in list of best sniper rifles and list of best machine-guns?

Also i intresting in any information about v-94 12.7mm sniper rifle.

thank you

in my personal opinion just about the best MG is the AK-47 for its rate of fire and durability. but its accuracy sucks.

the best WW1 and WW2 sniper rifle was the springfield sniper rifle.
and a new edition to sniping was the german G43 semi-automatic sniper rifle.

i think it was the G43
