Cubase 6: HSO vs EWQLso


I have a question:
Which VST is better inside Cubase 6.0.3?
Halion Symphonic Orchestra or East West Quantum Leap symphonic orchestra.
I mean CPU load, sound quality, number of instrument presets, etc.

My HSO sound is very soft… (i had to turn my volume to max…)
EWQLSO works fine (sometimes buggy when i try to open it from the VST plugins list )(F11).
