Leaving aside the "what's the best disc, period" question, and limiting ourselves to "what's the best disc that regularly goes on sale in stores for $25/100", Sony is my vote for most compatible/least problems right now. Verbatim used to blow Sony into the weeds, but they abandoned their "quality first" stance and are now competing to be cheapest in the weekend "Best Buy" fliers. Verbatim is not what it used to be, and even more annoying its totally inconsistent store to store, spindle-to-spindle. Sony may have its issues, but so far they remain more predictable and much more compatible with aging standalone DVD recorders. If you're burning on a PC, you can go with Verbatim, no problem: PCs can handle the many variations. But standalone recorders are increasingly choking on the newer Verbatim retail media. TDK, Maxell, Memorex and store brands have long since stopped working correctly in older standalone recorders: don't bother with them.
Taiyo Yuden (TY) is the last truly solid, made in Japan, utterly reliable disc. But they are only available thru mail order- you cannot just run to Walgreens or Circuit City when you run out of blank discs. Also, they cost about $37 for a 100-ct spindle, delivered. This thread is more oriented to "what's decent that goes on sale cheap all over town?" For those users, Sony is still a good choice. (I picked up 400 more during the last sale at Staples: my important recordings get burned on TY and then duped onto Sonys as additional backup, the Sonys are also my "give away" discs.)
