they have no point in tuning if you have the money just buy an EGT and use it to help you with your mixture

Greedy uses a 0-3V scale to determine A/F ratio, whereas the Autometer uses a 0-1V scale. So yea, GReddy would be more accurate. A wideband uses 0-5V, and is the most accurate, but be prepared to pay $250 for a new O2 sensor every 8-12 months.
Also, the EGT is kinda ackward, because many things can cause a rich/lean mixture... not just A/F.
