Whilst on holiday in the US, I compared a copy of the local US white dwarf (issue 319) and the UK white dwarf (issue 320 - the UK equivalent issue). This comparison is a little outdated now, but is archived here for future comparison and notes as a historical curiosity.
US White Dwarf 319
Before I get into the content differences, a note on the magazines. Both are the same paper size, but the US one uses cheap, thin, glossy (women's weekly magazine) style paper, whereas the UK one uses a thicker, nicer, satin style paper. The UK issue is higher quality (my US issue is already dog-eared but the UK one still looks fine and both have had similar treatment). The US issue costs $6 (about £3.20) and the UK issue costs £4 (about $7.50).
I have used the same standards for counting content. I only count actual articles as content. New releases, adverts, ordering information, store lists, etc are not counted as content. I count standard bearer as content even though it is basically an advert this month. Golden demon results (US) count as content. It is worth noting that the font in US studio articles is fractionally smaller than the central studio font (about 1 or 2 points smaller). The editorial is not included as content, neither are the tables of content. News and specific store events are content. Article cover pages are not content unless they have the start of an article's text on them.
UK number of pages: 132 including covers
US number of pages: 156 including covers
UK actual content pages: 71 (61 non-content pages)
US actual content pages: 114 (42 non-content pages)
UK content percentage: 53.7%
US content percentage: 73%
UK price per page of content: £0.055 / $0.100
US price per page of content: £0.027 / $0.052
Now a comparison of the content in each. The format given below is page, system, content title, my personal rating out of 10, and an asterisk is used to mark if the content is the same in the UK and US. Note that I like 40K, blood bowl, necromunda, BFG, epic, warhammer and mordheim in that order. LotR is not really my thing so bear that in mind for my biased ratings.

Average Score 6 / 10, 20 distinct sections/articles
Half the magazine was not content, the remaining content was fairly poor. Enough has been said about this issue on this forum that I dont feel the need to comment in detail. My arbitrary score is 3 / 10.
Editing was not as consistent as the UK issue. Page numbers point to articles that are not there in a couple of places. The US studio content, though only 50% of the issue, was very good and took about 90% of the time I spent reading this issue. US content is formatted like the UK WDs of old, with proper 1-turn at-a-time battle reports, small text and long articles. My arbitrary score is 7 / 10.
Well the numbers are obvious, in terms of content, the US white dwarf represents twice the value of the UK white dwarf! The UK studio content is not great and there is not much of it. The central studio content (assumed to be the content which is in both issues), is terrible. The UK white dwarf has a terrible amount of non-content. The US studio content is excellent. Fire the UK studio, make the US studio the White Dwarf overlords!
