It's a pretty great option, I think! Acorn doesn't get as much press, but it's really powerful for its price.

Also, while people are even more likely to forget Graphic Converter since it first came out in 1859 or something (this may be a slight exaggeration, but my point is, it's been around a long time), it has some neat tricks up its sleeve. I sent business cards to a print shop that required CMYK PSDs by doing the work in Acorn and converting in Graphic Converter.
