This is a very valid point, the other day I was looking for a wifi sniffer tool because I was getting terrible speeds over the last couple weeks and I wanted to ascertain the cause; there was nothing recently put out that compared more than 2 products, nearly all the blog posts were from 3-4 years ago, and the tools they compared were either bought out by cisco and the like or went out of business/ended support. really just having this type of list would be huge.
