These VSTs are really not bad.
Of course, some passages are always a bit difficult in terms of realism, but in the legato (so far I have listened to the violin and the cello) they perform very well.
For me, there is always an excessive use of reverb; if a sound works, it can be used even in dry mode or with very little reverb.
Besides, the developers are Italian.
