While Kant's criticism is phrased (somewhat obscurely) in terms of the logic of predicates and copulas, it also makes a plausible metaphysical point. Existence is not a property (in, say, the way that being red is a property of an apple). Rather it is a precondition for the instantiation of properties in the following sense: it is not possible for a non-existent thing to instantiate any properties because there is nothing to which, so to speak, a property can stick. Nothing has no qualities whatsoever. To say that x instantiates a property P is hence to presuppose that x exists. Thus, on this line of reasoning, existence isn't a great-making property because it is not a property at all; it is rather a metaphysically necessary condition for the instantiation of any properties.
