What paid relays am I using? Well, mostly the same ones that I've been using for 5 months with the exception of the @npub1vxfg5... BitBlockBoom relay. All of them have been very stable and work quite well.

Why use a paid relay?

That's simple! I like to pay for services that I'm using. I know that running equipment costs money. Also, using paid relays allows me to reduce potential spam in the Global or Universe feed.
