First drive you listed - If you look at the "pictures", look at the Included disk - it says Cyberlink BD solutions. Note high #1 (26% but relative small sample #, 23) - didn't read
2nd Link (LG) This is a "retail" version (Not OEM) - only 9 reviews, But reading some indicates it comes with Cyberlink Ver 8
As for the "tomsHardware review" good reading, but left out one key test - Quality of burn Didn't see it mentioned, scanned the responses, See someone else notice that.

This article seemed mildly interesting but any comparison of disk burners that only looks at speed and not quality, i.e. recording errors, is not worth the time to read, let alone write. Really guys! You're supposed to be the hardware
experts and you don't know this? Burners are judged on recording quality

To me Quality is more important than speed, And while this is to a large degree dependent on the Disk, the Burner does contribute. - You can see hugh differencies between different brands of disk and different burners when performing a quality scan (Most of my scans are on DVD+R disk.)
