What's a marksman? . . . But seriously, marksman is really cool as a concept, sniping enemies for massive damage, but they are more difficult to play effectively and still deal less damage than a bowman Plus, hurricane might be the coolest looking skill in the game, IMO
Bowmasters scale better as you level up since hurricane is affected by atk range Marksmen dont scale that well since snipe has a fixed damage but you dont need as many godly equips as a bowmaster to reach your full potential So it comes down to preference and fund
