Why do some safety razors feel too aggressive?

Aggressiveness refers to how much blade is exposed and how much it gaps from the guard. Community reviewers explain that more exposure cuts hair faster but raises the risk of nicks and burn if your angle or pressure is off. The Manscaped Plow 2.0, for example, is flagged by several r/wicked_edge users as too aggressive for a first razor, whereas mild razors like the Merkur 34C and Henson AL13 are far more forgiving.
