All good points but… don’t throw out comments completely. Even if you don’t get link juice in terms of Google, a thoughtful, engaging, and useful comment can generate some traffic from curious readers who follow the comment thread. It’s all about the “indirect” link juice you can generate. Furthermore, a guest post takes much more time and effort to create and promote. You have to factor that in as well.
