The team was given early access by StabilityAI to SDXL0.9 for this. You'll have to test it out for yourself, if you're interested in comparing. From my experience, it is a world of a difference between the NovelAI and WaifuDiffusion models in both quality and prompt understanding.
Note, the very baseline I set for the WaifuDiffusionSDXL model was to beat their SD2.1 based model[0], which it did not in my opinion.

SDXL0.9 may have been a worse starting point than SDXL1.0, and certainly there's been more time put in and experience developed finetuning SDXL in the time since WD trained against SDXL0.9 by the people who have released the huge pile of finetunes that have been released since.
I have not heard about the team upgrading or downgrading from the hardware mentioned there, so I assumed it's still the same hardware they use.
>SD XL just came out a month or two ago
About 4.5 months actually.
For the SDXL cannot be finetuned efficiently claim, an attempt at a finetune was released here: https://huggingface.co/hakurei/waifu-diffusion-xl
