When I stopped playing four years ago I had a bunch of VSTs. I've diligently not got into investigating VSTs since returning to play because that way lies madness and have been using the VSTs I have and the now ancient hardware that I bought for VSTs then. Thank you apple for bringing out the new M based chipsets soon after I had spent a fortune on an Intel Mac Mini with 1TB internal drive and 32GB of Ram. If I was going to try out anything new my big concern would the new (for me) VI Labs modern D work on my now ancient hardware that I'm not ready to replace yet.
But I had come to the conclusion that there is no just "the one" VST but whole library of VSTs and you can pick and choose which one you want for the situation you are in. I think this is the crux, which VST works best for the current piece and switch when necessary. But this means knowing your VSTs well.
Since I've returned to playing, I started with the VSL Bösendorfer Imperial that is the most forgiving of my VSTs. But since then I've spent considerable time playing the now very ancient Vienna Imperial from VSL, plus more recently the VC280 and currently am playing the BlĂŒthner.
The Bösendorfer Imperial is controllable with a good dynamic range and has a decent growl but overall for me is somehow lacking, I don't connect with it. If I want to get a recording it will be the first VST I can get a recording without glaring mistakes or sudden loud or ghost notes since it is so even.
The Vienna Imperial is such a rich sounding piano, and it has great una corda samples, but the dynamic range is not great over the full keyboard.
The VC280 is an interesting beast. But can be harsh and metallic in the upper registers if fortissimo. But overall it is lively, has real character and I like it a lot.
The BlĂŒthner is by far the most quirky of the VSTs from VSL. In some ways it sounds more real like an actual piano than the others, but it does lack in dynamic range and is definitely not even over the full key range.
I've got a couple of other VSTs that are hardly used. VI Labs Truekey german D which has very little sustain, but I do find works ok for pieces from the baroque/classical crossover period that are very busy with lots of notes.
And the worst I think is the Ivory II modern D that is just way to bright.
