ジャングル is a direct loanword and feels modern and familiar. 密林 is a native word that emphasizes density and can be used for any thick forest, not necessarily tropical. In everyday speech, ジャングル is more common. In formal writing or literature, 密林 may appear more often.
森林 means 'forest' in general and lacks the sense of tropical density. It is too broad and not a good translation for 'jungle' unless you specifically mean a managed or temperate forest.
