I'm not aware of any Protestants that see the Pope as important except in a very negative way - that's practically the defining feature of Protestantism and one of the few things all the Protestant denominations have in common, whether "low church" or "high church".

Heck, it's a struggle to convince many of them that Catholics are Christian at all, and "the Pope is the antichrist" used to be a normal, mainstream comment in American newspapers.

It is somewhat a piece of irony that the Pope generally holds a more favorable reputation in the minds of the irreligious in America than the religious. Even the average Catholic likely does not have as much respect for the Pope as some of the commenters here.
