Pence vs. Trump argument:
On Foreign Policy, Pence's competency would be far more stable. However, his Judeo-Christian fanaticism might me we end up at war at Iran for vague "reasons" that amount to allying with the Saudis and him wanting to go to a crusade with some Muslim nation. He's less likely to cock-up things in Europe or in the Pacific, at least. Therefore, at least an improvement.
On Human Rights... Pence would not be as overtly racist in his policies, particularly against immigrants and people of color. However, he would be hell bent on attacking the LGBTQ Community. It would be about trading one kind of focused bigotry for another. Executive orders would be where Pence would take his worst shots at same sex couples and transgender Americans.
On Women's Rights... One brags about sexual assault. One actually wants to overturn Roe v. Wade and take a shot at outlawing birth control, if he can go that far. Policy wise, the latter is worse, but Pence would not be able to achieve any of these dreams with a Democratic House. So it's really a push.
