Syngular - what’s the verdict?

I have Ptq 9 Stage but may upgrade to Standard, and include Syngular as the extra instrument, with the intention of tweaking the factory presets and maybe trying to create new sounds.

I will mainly want pads, strings, synth brass and “standard” analog synth sounds. A few of the factory presets are good, and close to what I want. But can anyone who has actually tweaked Syngular advise whether it’s possible for the average user to create usable sounds?

I do have other options for the sounds (on iPad - King of Digital and Synthmaster 3 Player, for example) but I find Ptq is much more stable and usable as an AUV3 instrument, so I’d like to extend its use.

Other posts are quite mixed about Syngular. What’s the verdict?

Thanks in anticipation.
