Now more than ever. HotSpot has undergone some revolutionary changes in the past few years -- from the G1 GC through tiered optimizing compilation and all the way to Java Flight Recorder -- while the CLR mostly added some user-facing features with little internal progress other than RyuJIT, which is maybe comparable to HotSpot's C2 JIT circa 2005 or so. Not to mention the awesome work done on Graal now, HotSpot's next-gen JIT, which is another very big leap forward.
