No comparison
binary file is pretty much everything that is not plain text, that is contains data encoded in any different way than text encoding ASCII, UTF-8, or any of other text encodings, e.g. ISO-8859-2. A text file may be a plaintext document, like a story or a letter, it can be a config file, or a data file - anyway, if you use a plain text editor to open it, the contents are readable. A binary is any file that is not a text file - nor "special" like fifo, directory, device etc
