Comparison between Motorola processors and INTEL processors:
Intel/AMD processors are really about the same thing. They run the same software and operate in a very similar manner. AMD is often less expensive than Intel and depending on what you use a computer for one may be somewhat faster than other.
Motorola has been largely relegated to the 'also-ran' category of microprocessor manufactures since Apple computer stopped using them in favour of the IBM Power PC processor (Apple has since switched to Intel).
Motorola had an excellent 32 bit processor design years before Intel. Also, the design of Motorola 68000 processor line (from a programmer's perspective) was immensely better. The two main features of 68000 line that made this true were
1) Orthogonality of register access and
2) Number of registers available.
These aspects made writing code for Motorola CPUs much simpler.
