I have been eyeballing these two plugs for quite some time now. I have a Ergo Medium, that's too big for me to use. I try, I just can't. I was looking at the small in both brands and I can't decide which to get. Any insights from you fine people with WAY more experience than me?

Insights - Not new to plugs by any means, have several that I really like. Njoy Large is my "go to" but I also have a Hush 2 1.5, Snug Plug 4, WMCBP, and a nice glass one. I find myself kinda partial to the 1.5-1.75" sizes and not really looking to size up. I enjoy those size ranges, can wear them for extended times and they just feel GREAT! Is there any benefit to adding either of these to my collection? If so, which one?
