so now me being new to this KE and AE world i have a question in terms of value

lets say there is a ke70 and an ae71 both in identical condition which is worth more ?

as far as i can tell they are very similar (apart from the engines) but is the KE70 worth more because its was the original or...... is the ae71 worth more because it has the 4ac in it already and is easier to convert to 4age ! just wondering ...........
