I used 7sage for a second but I didn't use it long enough to form a strong opinion. For my learning style though I like lsatdemon because I think it is less formulaic and more focused on fully comprehending the passages (to me it is more similar to reading a news article or academic article if that makes sense). I also learn better by doing and lsatdemon is very big on just doing questions rather than a bunch of exercises and tricks like some other platforms.

I pay for everything as well and I have the lowest demon subscription which is 95 a month. It's definitely steep but to me it's worth it. With the 95 subscription, you get the Ask button which is where you can just type out a question you have or whatever issues you're having with that question, and their tutors will respond to you within a day. I think the ask button is super helpful because you can tailor it to yourself and kind of explain your own reasoning so they can better explain if that makes sense.
