I honestly prefer mythomax/mythalion over tiefighter for only one reason, which is the balance between actions and speech. Sure, I like tiefighter descriptive actions, but its speech is way too short, like, sometimes it doesn't even write any speech in the whole message!
Anyway, it's all personal preferences, and I really appreciate the efforts you put into these comparisons. Keep up the good work!π
I personally like and use echidna-tiefigther-25. There's also another good one which is Openhermes-2.5-Mistral.
