I also prefer to use Corel to design brochures, when compared to the other programs, just because I already have it and know it fairly well. However, if you're starting from scratch and money's no object, I do think InDesign and Adobe's creative suite would be a better option.
My reason for saying Adobe's products are better is because it's more popular and generally considered the standard in the design community. Plus, it, IMHO, manages color better than Corel across all of its programs and it normally doesn't have the glitches that I've encountered when exporting some files to PDF.
