I've tired both and could not tell any difference in views or sales. The old expression... six of one, half a dozen of the other. I usually am optioned for "shop" because I think I'm still improving in my work and I like the most recent images to be what is first seen. The customer (if serious) can figure out they can go to collections if they choose.
I've seen in discussion threads many times when a question is asked, "What is your favorite work?" and the artist replies, "What I'm doing now", or "My most recent", etc.
It's also more convenient for myself, when I manage images or when I'm doing a series of a subject and want to quickly find my other recent images to copy search tags or see titles that I don't want to duplicate or whatever.
I also believe most potential clients "search" via internet search words rather than find your gallery by happenstance and decide to browse through (in my case), thousands of images.
