I would say communism is worse if we are examining them ideologically. Neither have been practiced with great long term success recently (but what system has?)
Ideally I'd rather have a singular ruler surrounded by people of skill, intelligence, and motivation making decisions for society and implementing the tools for society to successfully pursue those goals, and citizens that worked their way up via some sort of meritocracy. The commie lovers point to criticisms of the Soviet Union and say its not how communism should work, but are all too quick to throw all the negativity of past fascist regimes at the feet of the "system" rather than the disturbing judgement of the individuals in power themselves.
People may be uncomfortable with the idea of fascism, as it does imply some sort of aristocratic rule, but I believe mob rule is even more dangerous.

Which isn't to say that I am the least bit sympathetic to racist policies today. I am a civic nationalist, in the proud tradition of Theodore Roosevelt and, as the original Fascist, Benito Mussolini himself.
A nation can only be prosperous when it is moral, and a nation can only be moral when it is guided by moral leadership.
"God is the name by which I designate all things which cross my path violently and recklessly, all things which alter my plans and intentions, and change the course of my life, for better or for worse."
-C G Jung
Fascism by far is the more dangerous as it speaks to a compulsory forgetting of oneself under oppression. Communism as an economic model seems to count the individual, albeit a cog, as an important aspect of the whole.
"Not learning from mistakes is worse than committing mistakes. When you don't allow yourself to make mistakes, it is hard to be tolerant of others and it does not allow even God to be merciful."
