first of all, I suggest you buy your media online from shops in Germany or Sweden in order to get a reasonable price; it will cost you a third of the price in local shops. I can suggest some online shops if you're interested.
Verbatim is the easy choice for both DVD and CD media.
Taiyo Yuden is just as good (some would say better and some would prefer the Verbatims) but are only available online.
If you can get Verbatim 16x DVD+R media with the media code MCC 004, these are in general the most widely compatible 16x media and usually of very good quality. Some but not all online shops list media codes. If you insist on buying them in a local shop, any Verbatim 16x DVD+R that is marked as "Made in Taiwan" or "Made in India" will have this media code. Any verbatim 16x DVD+R that is marked "Made in Japan" will be manufactured by Taiyo Yuden and have the media code YUDEN000 T03 which is also good but not quite as widely compatible with burners as the MCC 004 media code. In any case you will have a hard time finding DVD media that performs better (in general) than this media.
Verbatim 16x DVD-R media will either be MCC 03RG20 (Made in Taiwan or Made in India) or TYG03 (Made in Japan by Taiyo Yuden) both of which are good and better than most other DVD media.
I personally see no reason to buy the Fujifilm DVD media unless you find it much cheaper than verbatim (very unlikely) and you care more about price than reliability.
For CD media I suggest you choose either Verbatim Crystal Super AZO (a.k.a. DataLifePlus), Verbatim Pastel, or Verbatim Extra Protection Made in Japan.
The Verbatim Pastel and Verbatim Extra Protection Made in Japan are both manufactured by Taiyo Yuden. This is some of the best CD-R media you can get anywhere. Most Verbatim Extra Protection CD-R media is made elsewhere (not in Japan) by other manufacturers and is generally good, but not as good as the type made by Taiyo Yuden.
If you buy online you can also look for Taiyo Yuden CD-R media.
