WebARCFOUR is very fast but less studied than many other algorithms. It uses a variable-sized key; SSH-1 employs independent 128-bits keys for each direction of the SSH session. The use of independent keys for each direction is an exception in SSH-1, and crucial: ARCFOUR is essentially a pad using the output of a pseudo-random number generator.
