The Current RADV/RadeonSI Performance With Mesa 19.1 + Linux 5.1

Following this week's testing of the Radeon Linux gaming performance between Ubuntu 18.10 and 19.04, I also ran some benchmarks on the Ubuntu 19.04 when manually switching over to the bleeding-edge Mesa 19.1 RADV/RadeonSI drivers paired with the Linux 5.1 Git kernel. Is that worthwhile for "Disco Dingo" users to gain better AMD Linux gaming performance?..
