Pence would be immensely better (which says how awful Trump has been). Foreign policy wise, we would revert back to standard operating procedure with Europe, Russia, China, North Korea, TPP would be back on the table. Domestically, the executive branch of government, the IC and justice sectors would be under less pressure to politicize, no more Twitter meltdowns, severely reduced Fox News douchbaggery with Hannity and friends behaving like a Pravda for the White House, democratic institutions like the media, rule of law, etc that Trump has spent time degrading would bounce back. Pence would of course still be a terrible President in the Ted Cruz vein, but he would be exponentially better than the utter Trash heap of a statesman that Trump is.
