If you can put some heat to the part you are trying to get off, I would do it. I would even sacrifice a bearing / bushing / pulley / etc. if required to save the underlying component.
I have a variety of brands of pullers (Harbour Freight [PA equivalent from the US], PA, CT, OTC, Proto, etc). There seems to be a differences in steel quality used and some threads seem to gall easier than others. I am 100% with using anti-seize. Hi pressure grease is not anti seize and does not protect the threads nearly as well as proper AS.
