I think the same.
So for me, like and zap are tools. They both can have different usecases.
Both can be overused.
At the end, the meaning is important.
Automatic stuff has less meaning.
If someone likes everything, it also has no meaning.
If you can like and zap, you can attach different meaning to them, compared to the "traditional" system.
Also the problem with likes is, its easy to "create" them. Maybe we shall add proof of work to likes to show that we mean that like by mining it. Would be an interesting concept. Still it would be "free" to give, because you only pay your electricity. You don't have to use additional money, but it would have kind of a proof in it.
