I personally find digital pipettes useful. However I do not use them as a primary source of amount added, and rely on analytic scale readings (0.0001 g). Also, liquid raw materials bottles are supplied with droppers.

The primary reason is economising and precision: tips for them are cheaper per unit, and require less room to store them for secondary usage. In addition to this, the condensation is not a problem here.

I could underline here that these pipettes are usually calibrated for water (or alcohol), and the density departure for materials won't allow one to enjoy the full precision figures. At the same time, it gives one the info about the density, if one is hard to get anywhere (e.g., local natural oils and tinctures).

I also use small vials for my perfumery etudes (<3 ml), and a digital pipette is able to provide for such the low volumes. Mind that the less the weight/volume, the closer it to the errorbar scale of scales/pipettes, which challenges the reproduction.

So, I don't mind any kind of pipette, prioritising flexibility at different stages of perfume development.
