Every stubborn synonym takes a side. Obstinate, headstrong and inflexible criticize someone for refusing to budge, while determined and tenacious praise the very same trait as strength.
So the choice depends less on meaning and more on how you feel about the person. A separate, everyday use covers things: a stubborn stain, cough or problem, where words like persistent and intractable come in.

A tone dial from praise to insult
The five chips run from compliment to jab. Determined is pure praise. Firm is neutral and calm, often used for a parent or a manager. Strong-willed can go either way: a strong-willed child may be a handful. Obstinate is clearly critical, and pigheaded is a rude, casual put-down.
If you want to describe a friend kindly, stay on the left. If you are complaining, the right side does the job.

Easy to confuse
Resilient is not the same as stubborn. A resilient person bounces back after a setback, while a stubborn one refuses to change course. Loyal also differs: loyalty is to people or causes, not to your own opinion. And strict is about rules you set for others, not about your own refusal to bend. See resilient synonyms for that idea.
The flexible side: antonyms
Flexible, adaptable and open-minded are positive antonyms. Easygoing and agreeable sound friendly. Compliant and yielding can hint at being too ready to give in.

- He became more open-minded after traveling.
