"change the title because it's slanderous."
Well in that case I can say with some certainty that you can tell them to go fly a kite.
If you want to cover your butt you could go with the change you suggested, it doesn't really take away from what you are saying. However as pointed out using the word "sucks" already implies that this is an opinion.
It isn't like there is a scientific method to determine suck levels. If you said something like "blah blah blah fails lab testing" then you better have factual data to back that up.
