Monserrate is certainly worth a visit, but we do like Colpatria for several reasons: the city view is better. For those entering the photography industry, Colpatria's photos are more interesting. Interested locations are closer and easier to see. - Very rarely busy in Colpatria. We just finished Monserrate on Saturday and it was very busy. There was a long route down the cable car. After Monserrate we went to Colpatria where there was almost no one. There was even some information that showed there and provided some background for key attractions. If you have your zoom lens you can get some good photos on the mountainside. On the downside is that I read Colpatria's opening hours are inconsistent and unreliable. It would be a very different comment if we got there and found it closed.
