They're not the same. Stick them in H10.measurements, and you'll see
that the center frequency of [bp~] can go above 1, while [vcf~] seems
to normalize the center frequency. There's also a considerable phase
difference. Try making a notch filter by subtracting the filtered
signal from the unfiltered signal, and you'll see that [vcf~] looks
like a notch, while [bp~]...not so much.
