I don't think it's as clear cut as that.  App startup time matters
for, say, CLIs (but who would make a java cli app...  well, except
ant, heh) and for GUI apps (which starts to matter a little more) but
not so much about some of the more interesting Java areas --
serverside.  I think at best the jury is still out on how fast gcj is
vs a hotspot-optimizing jvm for "real world" use.

It would be interesting to see some benchmarks comparing real-world
workloads and examples.  I don't know of any off hand, though, that
included gcj.
