Should i fix my s9+ ?

I've had my s9+ exynos since launch , a very great phone gotta say but i need an advice In my country the samsung shop near me is demanding 50$ for battery and 100$ for screen other that the vibration in my phone isnt working also .im keeping it either way

The question is , should i fix it totally ? Or should i go with note 9 clean for the same price of fixing with installing custom ROM

Thanks
