Model mixed (not regular merge, merging models itself messing with encoder too much) to be able to do wide variety of concepts that pony-based can not because of how training done and do it in drawing style because most of sdxl model either too realistic or anime tuned and lost ability to follow natural language prompts as original sdxl do.
Better used on 3-6 CFG 15-24 DPM2 steps.
More oriented in scenery and backgrounds for RP/as assets, characters and interactions better in pony-based model. Also pony-based can be used as refiner for sdxl or vice versa.
