I'm in favor of impeachment. Pence is god-awful, but he's not bat-shit crazy and not nearly the megalomaniac and narcissist that Trump is.
Trump is under the spell of Bannon, but Pence probably isn't. Trump favors the use of violence--most likely by way of police force--to get his way; this strategy is less likely to be used by Pence, who is much more of an establishment figure. Pence would probably back off of the idea of building a wall on the southern border, whereas Trump will pursue it out of spite.
Pence has experience in politics and is much more diplomatic as can be seen in his attempts to "clean up" after Trump--i.e., after Trump has made egregious statements. True, Pence would be awful on issues like LGBTQ rights, abortion, and marijuana, but his views are so far out of the mainstream that he might not be able to do permanent damage.
Really, this is all speculation, but I'd rather take my chances with Pence than with Trump.
