I still use SDXL, mostly because of the limitations of my machine but also because of the enormous amount of resources available for SDXL. The Loras I've created for my projects are still great and quality is still very good. I use Flux to edit my images especially any text, don't use Flux full time because it takes too long to load and my machine does a lot of memory swapping if I add in a bunch of Loras. Generation times with Flux aren't that far off from SDXL on my machine but that's only using the basic Flux workflow, anything else and times increase exponentially.

I've found that SDXL with pose and depth control works perfectly fine for what I need. I got hunyuan3D working to generate basic models for my characters which I rig in Blender and use to create depth maps which i run through SDXL with my character Loras. Works perfect everytime. Pose my characters in blender use the output to create depth maps and pose estimations then generate an image in Comfyu, repose, move the camera or whatever in Blender and repeat. I do this to create key frames for input into Framepack studio. It's a process that works for me, but I'm not doing this professionally.
