-I would say every C# evaluation libraries have drawbacks and benefits, ExpressionEvaluator is not an exception so choose wisely.

-The biggest difference of ExpressionEvaluator is that everything is evaluated on the fly, nothing is compiled or transpile nor in CLR/JIT nor in lambda expressions nor in javascript or other languages stuffs.
+The biggest difference of ExpressionEvaluator is that everything is evaluated on the fly, nothing is compiled or transpile nor in CLR/JIT/IL nor in lambda expressions nor in javascript or other languages stuffs.
 So it can be slower in some cases (sometimes not) but it also avoid a lot of memory leaks. 
 It already allow to evaluate some small scripts.
