Suggest me 1 analogue sounding 3rd party synth to complement my Logic stock synths?

Can you suggest me 1 analogue-sounding...

Until/unless you can define that with something more specific and tangible, you're not going to get any useful advice.

I have been wondering as well what analog sound means.
Maybe s/he means the types of sounds it can make.
I think most subtractive synths overlap considerably, like 90%.

So just get a very complete synth with lots of features, which usually translates to versatility. The sound quality as such is fine with most products these days.

Although it is like a decade old, Retrologue 2 is still my main synth. It sounds very good, is very versatile and also quite a bit cheaper than U-he etc.

Well, KVR's top popular listings are safe bets https://www.kvraudio.com/plugin-ranks.php?m=1

Analogue, whilst typically subtractive does not mean any subtractive synth will sound authentically analogue.

For analogue sound some synths are specifically emulations of analogue synth hardware and it would be worth looking at those. Do demo them though cause some of the analogue virtual instruments from bigger developers do not not sound very good to my ears.

Listen out for hard sounding "scrape-y" filters at high resonance and dull, muddy, cloudy low definition sound which pretends to be warm. Many more of these than you would think.

There are 100s of commercial subtractive synths that sound great but not necessarily analogue.

You can help them all to feel analogue of course, typically with some gentle pitch modulation.

Can you list 5 of your recommended synths?

In no specific order ones to demo for an analogue VSTi experience

Diva
LUSH-2
Bazille
XILS PolyKB
Repro 1/5
ANA2 mainly for its filters
