From that article
Yes, latex is probably the best bang for the buck upgrade you can ever make to any of your bikes. They are definitely more labor intensive to install than butyl, and you have to pump them up every day...but you can save 3-5 watts per wheel(!) compared to butyl. At the moment, tubeless is getting better, but still nobody has a tubeless system as efficient as a high quality standard tire with latex inner tube.
Putting it in perspective, that $20 latex tube at minimum would be worth maybe 3 watts in a front wheel compared to $1000 for the best ceramic bearings which might get you 0.8-1 watt for a wheelset upgrade.
That's pretty compelling stuff.
