I've been using Canon since the 1970s. My present film cameras are two new F-1n's. I have four of the five Canon finders to swap around depending on what I'm shooting. The eye level FN and the AE finder FN are the two I use most. The speed finder FN is heavy and I don't find it to be of much advantage over the other two. For certain applications, I use my waist-level finder FN-6X. When looking to purchase the best quality Canon film products I always shop Japan dealers.
