Welcome!
I’ve tried many chain lubes, from DuPont dry chain lube to sticky paste. Over my time I’ve found the best is Motul Chain Lube Factory line, I find it’s more clingy than regular motul chain lube but doesn’t create such a big mess. I switched back to it from the DuPont chain lube, while the DuPont was nice as it attracted very little dirt and created little mess I found it didn’t provide as good protection. By no means am I endorsed by motul I just like their product. In the end though it can come down to where you race and what fellow racers use, most all the time if you use the same stuff other guys/girls are using you’ll be just fine. Again I’m not sponsored by motul but their factory line paired with chain clean is great. I apply the Lube after every run except if I forget (which happens a couple times) but I’ve never had any issues, and apply the chain clean at the end of the day. But I can’t speak to Wurth chain lube as I have never come across it.
