Some less popular options to check out:
If you’re looking for something that sounds rather vintage, don’t sleep on GS Music E7. It’s considerably less expensive than most synths you’ve listed, but the build quality and interface are excellent. The raw oscillator sound is especially rich, lots of movement without using any LFO or modulation source. Only available as module though. And it has a ladder filter comparable to your Moogs, so no fresh air in that regard.
You might also consider waiting for Dreadbox Artemis. It’s comparatively cheap but will surely have the rich Dreadbox sound with an excellent filter that so many people love. It also has sliders, which some prefer. FX by Sinevibes should also be great. Both ADSR envelopes unfortunately share a pair of sliders though.
It’s also always worth thinking about Prophet Rev2. It’s cheaper than the other Prophets but has a lot more voices and modulation options. Also has a display that’s less cryptic than Prophet 6. And it’s multitimbral with splits, dual layers and individual outputs. Worth giving it a listen and see if you can spot differences to eg Prophet 6.
If you’re willing to go 500€ above your limit, Melbourne Nina and Arturia Polybrute 12 also come into play. For the extra money, both will give you lots of unique control options that make using them something special. You might want to look into these as well if you can afford it. I only have experience with Nina but can say it runs circles around every other synth I’ve ever used due to its motorized knobs, morph function, loads of in- and outputs.
And definitely check out the UDO synths!
