Malcador is a nice tank, but personnaly nothing can compared to the good old Leman Russ and its dozens of varaiants. I never really got into using Super Heavy tanks such as that and the Benblade, but it still has some marvel in being one heck of a mobile fortress.
Hehe, for me its the same, but I also choose to opt for the Tank Hunter, a Vanquisher model with only a las cannon and a Knight commander, brings fear to Space marien players feilding Land Raiders.
