I think this poll should be in DVD Talk shouldn't it?
Anyway, I feel unable to vote based on just those 3 choices but I have voted for "any" as the best of the worst
The reason is that I check out each disk before I buy and do a thorough region comparison on a feature by feature basis and then compare the prices.
Generally, I'll buy which ever region I can get cheapest, but ........
I one region is censored then I won't buy it (R2 of The Matrix for example), even if it's cheaper.
Also, I consider the sound formats, as they differ between regions too - and I don't mean whether it includes DTS, but rather, if one version is in stereo and another is 5.1 (e.g. Wild Things R2 is in stereo, Wild Things R1 is in 5.1).
Also, I look at whether a disk is anamorphic on each region (e.g. Bound R1 is not anamorphic, but Bound R2 is - both are uncut).
Lastly I look at the extras as these differ from region to region. I don't really care much for extras (with some exceptions), but if two different regions are the same price, but one has a few more extras, then obviously I may as well go for the one that has more.
I tend to buy a lot of R4 disks because of their price (and they are generally uncensored, unlike UK R2 disks). Sometimes they can have better specs too.
When you look at the grand scheme of things though, many R2 disks are uncut! It's just the odd one here and there so you really do need to compare them on an individual basis. In fact, it is more common for R2 to lose some of the extra features of R1 (but not always).
Whatever disks you have on order, just compare the specs with R1 and R4 and if those regions have something extra that you want, then get them instead. You can check whether a film has been censored by the BBFC, by checking their website:
www.bbfc.co.uk, and you should use region comparison sites like
www.dvdcompare.org.uk to check for this (and other differences) as well.
