This impacts me in a somewhat strange way: usually palladium is cheaper than platinum, so when making platinum/palladium prints you can use more palladium both for controlling tone and to spend less on chemicals.
All the detail you might ever need from the excellent work of Mike Ware: https://www.mikeware.co.uk/downloads/Platinomicon.pdf
The process has beautiful gradation and extreme archivial resistance with correct paper choice (but despite what you might read about it it's not the absolute best at that, because platinum is a catalyst for reactions that you don't really want to happen in your print over long timespans - the best would be the even more niche chrysotype process).
Personally I'm dialing in my approach to eventually make combination platinum / cyanotype prints (I use digital negatives, one of the issues with these alternative processes is that you can't enlarge, so they need either large format film or a digital intermediate).
