Are Greatswords really better than spears for frontliners ?

So I was looking at my gear (second run, still mostly bronze gear) and at a few posts saying Greatswords are the most balanced 2H weapon stat wise. Except when I check my inventory spears are just slightly behind in damage (like 1-3) but comes with much better speed and accuracy to the point I wonder if my knight wouldn't be better with a spear rathan than a greatsword (don't need the shield currently, might swap to it later)
