Good choice; especially with the H910/H949 algorithm included.
As far as the algos within PitchFactor pedal go, I probably use the HarModulator (parallel harmony with modulations), Diatonic (scale constrained harmonies with delay lines), and PitchFlex the most. That is, beyond the two that you already have.
It depends on what kinds of pitch processing that you're after. The PitchFactor algorithms are pretty much all different & unique. It's a multieffects pedal for pitch.
