Nixon resigned just ahead of a vote to impeach that would likely have led to removal.
If not for the pardon, Dems would have impeached after he left office, and then prosecuted. I doubt you remember, but there were meme-like cartoons of Nixon being a prison bitch, and demands that he go to jail.

Bill Clinton didn't have sex with Paul Jones, nor did he "take advantage" of her. She said "No" and that was the end of it. Her case was dismissed for lack of evidence. Her lawyers appealled the dismissal and Clinton paid her lawyers to go away. Jones received almost nothing because she had no case.
