I have a budget of $300 for a filter. I have narrowed it down to these three. Which one do you think is the better filter?

If you all have some other filter pedals in mind, feel free to say it. Thank you.

I'd say the Moog, but I've heard good things about the E-H one as well. Find a shop where you can play one.
