They have very different advantages, first notable difference is that the Akai is a dual filter that you can feed the mono into the stereo, or have them running parallel - and filter the signal twice with any combination of HP BP LP etc you wish, this makes it a much more versatile bit of kit with a far greater range and sonic pallet…the Akai is a little noisy with a very strong flavour or character, you wouldn’t strap it over a stereo bus and impart that character on an entire mix but you could do that with the cleaner, more transparent electrix (with low resonance).
The Akai sound is very nice with high resonance and self oscillation, its almost “303” or “Korg Volca Bass” like when resonance is even a little cranked, it keeps the low end and the tones generated glide between each other. And it has a wide sweet spot. The electrix gets a little nasally with high resonance and can definitely make your ears bleed, it has less sweet spots that are not necessarily near each other on the spectrum, its sounds more like a cem or DSI filter but not quite…
The best thing about the Electrix over the Akai is its ability to track pitch from midi note input, so you can have the pitch of the signal you are sending through it “harmonised” with the pitch of the filter…that is neat…
The best thing about the Akai over the Electrix is the triggerable envelope…its very snappy and MIDI controllable…its surgical and can slice and dice your signal like a ninja. The Electrix is less responsive with MIDI in this regard but still very usable…BUT…it has CV in for the filter!! Soooo if you have say an A4mkii that you can control the filter with it, so you can out ninja the Akai.
The distortion on either box is garbage and does nothing good to the outcome, best avoided.
If i had to choose its would be the Akai, but if i got to choose any outcome, i would build a custom eurorack dual filter with some modulation modules and a sequencer…no oscillators (other than to modulate the filter) just a dedicated eurorack desktop filter box.
