Honestly it comes down to how “accurate” you want her outfit to look from the right accessories to the right shade/color of the pants and shirt. The weakest one is the swtoys imo, every is under scale but the boots might work on some bodies while others like the HH look “bulky” just like the MMTToys one, also come down to some boots being “brown”. The SuperDuck gear is inaccurate from the belt to the boots, they have a heel instead of being combat boots and the gear uses more of the cheap looking pleather from the knife sheath to the drop leg holster and “duty belt”. But the super duck clothing is tailored better and not as baggy as the MMTToys but I do like most of the MMTToys gear though… the HH isn’t bad minus the lazy reused of the Leon holster and their Jill 1.0 set, also the knife sheath is also inaccurate as well if you have the swtoys or MMTToys set/figure use the that knife instead. Besides the Hot Heart blue tank top being absolute trash the pants and white tank aren’t bad the jeans are a bit more darker than the Super Duck ones as for for sculpts… well, that all depends on the collector and what they prefer or looks like reimagined Jill. I will say MMTToys wins… follow by HH but the sculpt on some bodies makes it look like a bobble head, which it’s the exaggerated hair piece then I guess swtoys? Lol I like the super duck sculpt for classic Jill customs since it had the mature look to it. It just comes down to what shades, colors, tailoring, etc you like better. The only thing I used from MMTToys was the gear and sculpts, the clothing was too baggy… the swtoys one I just body swapped for a joint body one since the stock one was too lanky, the super duck set I replaced some of the gear and boots and the HH I didn’t use the stock body, pants, boots and gloved hands since they reused the same ones from their first Jill set( I used the extra ones that came with the Super Duck set since it matched the pale looking sculpt). Hopefully that helps.
