There was a version of the TN4A with an XP-L HI. Perhaps that is what you are referring to. With the XP-L and the OP reflector my TN4A has more flood and more throw than my SC31B with the SST20. My C8 silver with the XP-L HI SMO out throws both of them. The hot spot on that is so bright that I can understand your comment about it not being a good leash walking light although I did that for quite some time and didn’t realize how bad it was.

OTOH, I think that these two examples of single 18650 lights and the TN4A AA are fairly similar with the TN4A having the widest beam and the C8 having the farthest throw. Size and weight are biggest things that make it different. Of course what I like are the UI and the tint and something similar can be found in many different lights.
