I Am a Strange Loop is for sure the least technical of the three but it's best if you read it last since it's a very emotional and touching denouement to the other two books. You can read GEB or MT in any order, perhaps MT might be more approachable to start with since while it is quite technical, it's a series of articles that can be read independently of one another and each article has a bit of an aha moment, as opposed to GEB which is one loooong marathon where the aha moment is absolutely enormous, but requires a great deal of preparation.
