After checking a while i think a best oregen is a vein one. Work is done. I decided to separate ores to rare and common.
Rare is mese, diamond, chromium, gold, silver, mithril and uranium. They will be generated below -300 as a single nodes forming a chain, but separated with 3-4 blocks of stone.
Common ores are coal, iron, copper, tin, zinc and lead. They will form a continuous line 2-5 nodes in diameter below +100. Vanilla scatter oregen is removed.
Related screenshot illustrated oregen (for research purprose i allow ore replace air with unlimited height):
