The Bomb DVDs have better quality (video quality) than the sabras, but sabra releases DVDs twice a month and not twice a year like bomb does. (actually, the video quality in the sabras has increased lately, and most are the standard 8,000~9,000 bitrate)
As for the back issues, I can just order them from local shops...One of the perks of living here and having a Japanese postal address, but I honestly don't know if I'll bother with the Bomb DVDs anymore. Collecting one gravure mag is enough for me (still one too many according to my wife sometimes)
Even if it's only twice a year but at least you know that it's always something good, I guess, unlike Sabra (some of the amateur or "fresh" girls featured are just hideous-looking, and that's putting it kindly...). It's nice being able to order back issues easily, i think I will have an avalanche of magazines in my room if I could do that too (although I am already running out of space to put them now!). On my trip to Tokyo I found that Jinbocho is really the No.1 place to look for magazine back issues, there were so many second-hand shops along one of the streets. Although I couldn't find the magazine that I was looking for (a Hip and Lip with Meguru Ishii on the cover) but I ended up buying back issues of quite a few others.
I like the "Latest Electronics" section the sabras have. Looked through BLT before, and didn't like it..Too much H!P/AKB48 type stuff, which I have no interest in at all. I found them to be almost as bad as the "up to boy" mags.
Ah I'm not a tech whiz so not too much interest in those. For BLT I usually skip the HP stuff as well but i do have a little interest in AKB48 (although not to otaku level), but I haven't ever bought any UTB at all (they could almost just call it H!P magazine).
My main interest in BLT is they always feature interviews and photo shoots with the leading celebrity actresses like Masami Nagasawa, Saki Aibu and Aya Ueto (although it's Leah Dizon this month...) and they have gravure idols like Yuzuki and Meguru at the back too, which I thought was a great combination not found in most other magazines which normally focus on one or the other. And I find the monthly celeb profile section useful to since they always keep it updated with their latest shows and releases.
I think Bomb would be better if the magazine size was bigger. Gravure shots doesn't good as good if it's pocket sized, damnit!
