I can't say which version of WebKit is faster because this is
confidential but Blink uses a mark and sweep type of GC, which is pretty
much the cutting edge technology:

So you cannot tell us if Blink is faster on the same CPU as you tested WebKit?
Well there's WebKit, WebKit2, Blink, WebKit for Wayland but I can't
share the results of the benchmarks. The renderer differs so some are
faster but the bottom line is they all use a mark and sweep GC running
in a different thread.
So how can we know that this cutting-edge GC will make things better?
I am not saying Blink GC will make things better.
Note: I am not saying that we shouldn't adopt better technologies that improve
performance, even if just a little. I am simply debating your claim that the
GC is the whole reason behind the slowness.
Personally I just want the Javascript / QML to be blinking fast and a
mixture of one of the aforementioned renderer, QtQuickCompiler
on-demand, a decent CPU architecture and root_ptr could definitely get
the job done once and for all.
