I would say there is an ambiguity in the term better, which is not properly defined.
The term better has to be defined in terms of measure. What is preferred has to be measurable, or else it is not an objective argument.
In the first premise, better is taken in a very narrow definition, while comparing rational capacity of beings, where reason is preferred to no reason.
In the second premise, better is not in regard of a measure of anything but a property of the Universe.
