Who is your favourite quant publisher and why?

Hey everyone,

I’ve been a big fan of Unsloth for several reasons:

• They publish models ASAP after release.
• They usually offer the lowest PPL.
• Their website has tons of helpful tutorials and documentation.

Recently, I stumbled upon this Reddit thread suggesting to try out an Apex MoE quant of Mudler instead:

So I decided to test it myself. I tried running Qwen3.5 122B IQuality, which is roughly the same size as Qwen3.5 122B Q4_K_XL. So far, I haven’t noticed a difference in real world tasks between these two models in terms of output quality so i decided to run one gsm8k benchmark and unsloth was slightly better.

So im asking you now, who is your fav publisher and why?
