Tim first introduced his comparison basis (Scaling, Dev Tools, Dev Speed and Maintainability) and explained his views on the 4 topics and which keywords he considers under each of them. This introduction was really good and well-founded. After that, he showed and explained a diagram to make the actual comparison.
There is a graph included in the post to help make his point in comparing the three languages (PHP, Ruby, and Java) on how well they can perform. PHP bested the rest in Dev Speed and Maintainability, but lost out in Dev Tools and Scaling abilities. Tobias has a few disagreements with Tim's findings, particularly on the topics of Dev Speed and Maintainability.
