Thanks! There used to only be a few of these, but now there are quite a few, hopefully mostly using their own data sources. 

There is also https://knotsgoup.vercel.app/ which uses the Bitnodes API.

Looks like BitMex spun up a little Bitcoin node client tracker:

There is also Luke Dashjr's [node client tracker](https://luke.dashjr.org/programs/bitcoin/files/charts/software.html?2)

As well as [the one run by BitNodes](https://bitnodes.io/dashboard/#user-agents)

And there is [Coin Dance's node tracker](https://coin.dance/nodes)

And [something called Bitref](https://bitref.com/nodes/) (which I had never heard of before)

And [Clark Moody's dashboard](https://bitcoin.clarkmoody.com/dashboard/) exposes a little info about node clients as well
