If it’s ladder filter you want…get the Moog. It’s one giant sweat spot and nothing will ever compare to beutiful Moog analogue oscilators driven just perfectly into a ladder filter - you just can’t compare the two architectures though, the Moog is just built to sound like a Moog…
If versitility and a vast pallet of sound is what you want. The A4 wins hands down. The dcvcos “or whatever” driven into the Elektron filter won’t get you the Moog sound exactly, its not as hissy / spitty / gnarly…
but it it will give you 20 times the pallet of the Moog, it is more polite at the level of osc into filter. I think…but you can go more places without the imprint of the character of the synth becoming to obtrusive.
I’m a fanboy of both Moog and Elektron…
But this is not Twighlight and I’m not K Stewart…i can have the vampire and the warewolf🤣 if I were you I would simply get both and be happy.
