Boreal rubber has had a poor reputation since 5.10 came on the scene (I think).
I have had several pairs over the years, and currently have a couple of pairs of Spiders. The rubber is definitely a different consistency to other used by Scarpa, Red Chili and 5.10, but different is not necessarily bad. I find that the Spiders are not that great indoors on polished plastic, but they seem to stick nicely to polished limestone. I suspect that no one rubber is the best for every surface.
So, for hard limestone sport climbing I will wear my newest Spiders, but for the wall I will wear some Red Chilis, and for hard grit/granite bouldering I will wear my Evolvs. For general cragging, I will wear whatever is comfiest as the type of rubber you have on your feet doesn't make a huge difference apart from when you are really pushing things.
