Vitals best feature imo is the ability to create your own wave tables through resynthesis. By adding modulations and effects in the synth (inc those spectral effects) using LFOS you can resynthesize the result into morphable wavetables. Some greate sounds can be created that way. You could even resynth your own drum hit presets and play them back like samples.
Also don't forget single cycle wavetables are allowed to be imported. I've had a lot of fun recently creating some from my favourite hardware synth plugins.
Wish vital allowed multiple single cycles to be loaded to create morphable waveforms. Serum can do this but unfortunately vital can't.
Wishing you all a happy holiday
