"That is correct, they are not the same thing. That statement is coming from my use case, where I, have so far, only use them for manipulating objects during run time."

So here's my main complaint: If you know that these things are not really the same, why do you present them as if they were? You would have had a much more favorable reaction had you been more upfront on your biases, limited Ruby experience, and narrow focus for comparison.

Because in my eyes, they all serve this purpose: "That means you have access to the inner working of an object."

Whichever technique I choose to use does not matter.

I am using my blog the way blog is intended to be used, as opinion piece, I had no attempt in hiding my biases, but there's no need to purposely be biased as well because I like both and make a living out of both.
