According to its helpfile, [vcf~ ] is the same as [bp~ ], but with a voltage controlled aka signal rate inlet for frequency.
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.
