Gothmog, Morgul Lieutenant vs Grima, Saruman's Footman

So I have a [[Saruman, the White Hand]] deck that consists of LOTR cards only that I really like. I was looking at potential changes or upgrades and came across [[Grima, Saruman's Footman]] which I already have in my collection. It seems to fit pretty well in the deck but I struggle to find something to cut. It made me question whether [[Gothmog, Morgul Lieutenant]] is a good fit for the deck since the deck only makes orc army tokens and wraith tokens. Is a large army token more effective because of deathtouch? What are your opinions on these cards?
