I believe the difference in moving parts between a combustion engine and electric motor is about two orders of magnitude (20 vs 2000). I would say "practically no moving parts" is an ok term in relative comparison but thats just my opinion. There isn't really a debate, as far as size, weight, complexity and maintenance electric motors win over combustions engines. The problem of course is the battery size cost and weight compared to a gas tank. Bottom line though electric cars have much less maintenance and much of that can be attributes to much less moving parts.
