Experts don't care about usability or convenience, only security. I use password algorithms because managers are so darn inconvenient. Especially when I need to type my password into an Xbox, for example, or on my wife's computer real quick. I believe my algorithm is strong enough that it puts me completely out of reach against automated attacks. If one password is compromised to plaintext, will an attacker even recognize it was generated by an algorithm? Unlikely. If two of my passwords are compromised to plaintext somehow will a determined attacker specifically targeting me be able to recognize and determine my algorithm? Possibly yes. But in my mind, the risk of being individually targetted and having two different passwords compromised to plaintext is not high enough to outweigh the convenience factor of password algorithms.
