The main point here is the feature list. The Ranking isn't to take much seriously... but may help to some novice.
Wow, incredible work...
Thank You
I know they all have their strengths and weaknesses,
Yes it is. The main point is what features are more important for an user or a project. Each one should make his own scoring table. Even Sampletank can have its place.
but please let us know what you are rating as the the best overall in features and stability for moderate to large projects...
I have to remind that we are talking about VST plugins. If you are using Logic 5 or 6, EXS24 probably will be the best option.
Once said that, I think that in the VST arena, the battle is between Halion and the NI couple.
In my opinion, for a moderate project Halion should do the Job very well. But if a work huge depends on a sampler, as mine usually does, ( with Orchestra and Choirs) Kompakt is the best. Because it allows a lot of details that huge increase the realism and usability of a sampled instrument: like group editing, key switches, mod wheel Fades, Round Robin ...
But even Kontak have some extra features than Kompakt, I think is slow and less easy to use than Kompakt, so I use it just when need some complex edition of a Kompakt instrument. But I don't have even instaled as VST instrument.
The overall winner is...
Despite the table gives to Kontakt the number one...
I prefer.... (sure you guess right): Kompakt
