Interesting perspectives - and i wholeheartly agree with your last paragraph.
While i do agree Supermans physical stats are slightly greater than Thors and Thors versitility is greater than Supermans - which makes them extremely close peers - i guess i viewed the question a little differently - i envisioned Odin as a battery with 100% juice or an old D&D character with 100 hit points and then compared those thoughts against the other characters to determine power levels.
Or if each characters (equipment included) were being drained by some nasty villains power draining machine - which character will have the most juice to drain?
But this is one of the reasons i love this board - how we are all asked a question and the different ways we come to our answers (for the most part anyways until a Hulk-Thor or Superman-Thor debate begins in whatever new creative way it gets brought up and then consumes everyones time and thoughts).
Superman has true flight and Flash mode, how does Thor counter that?
