Really, whether you should get silver tops vs printable vs whatever finishing on top is up to personal preference. Any genuine Taiyo Yuden media should be solid regardless of the finishing. As for which ones to buy, it's a little vague of a question but it depends on what type of burner you have (like how fast can it burn), what firmware, and what you are planning on putting on your DVDs (backup of movies vs data...etc)? Let's say that you have a 16x capable burner and if you live in the U.S. the fastest rated TY media would be 1-8x media which can be burned at 12-16x without too much problems. I'd recommend you purchase the DVD+R (YUDEN000T02) and then bookset it to -R if you need to have better compatability for stand alone DVD players.
If you live in Europe or Asia, you can probably find TY 16x DVD+R media which is is YUDEN000T03.
Edit: Looks like you can purchase TY at 16x from that list
