Triage rules, they make massive tunage & basslines. I can hardly get my reeses to sound that good but here are my 2 cents.
The key here is having a lot of movement, so anything goes : notch filter, phaser, flanger, chorus, frequency band shifting in a multiband distortion plug like Ohmicide, vowel/phaser filters (Kontakt), ring modulation, reverb, everything you can think of.
But you do not want to go too crazy on the wet/dry knob, it's better to add a small amount each time so it doesn't get messy after using a couple of effects.
Also, in my experience it's better to resample everytime you add something rather than having long effects chains. That way you have many versions of your sound so you can always go back to a previous one that sounds better and you also have better control over your sound.
Imo splitting frequencies is useful for keeping the sub+bass area clean & compressed but for upper frequencies, multiband distortion and careful usage of other effects makes splitting unnecessary (perhaps it'll have more weight if I tell you Noisia only splits in 2 bands as well). So usually I cut at 150 Hz with a very steep filter so there's no gap between the 2 bands. Mono the bass band and compress to get rid of the volume amplitude due to the detuning. Other effects go in the upper band.
Also, distortion and other effects bring out unwanted frequencies so it's important to EQ your sound regularly. Parametric EQs are best for this, set a narrow Q, boost by 6 or 9 dB, sweep until you reach an unpleasant spot then cut by the appropriate amount. It makes it easier than cutting then sweeping.
Personally, it took me a while to start having an idea of where to cut. A/B with professional basslines may help.
