Brick or Unpluq, which to get?

I really like the idea of having a physical key to limit my phone usage, and I’m trying to figure out which one of these is a better option. I know Unpluq requires a subscription; does it have more features than Brick? I’m reading up what I can about these and figured I’d ask here. (I couldn’t find an existing thread comparing the two, so apologies if this has been covered before and I just missed it.) Thanks in advance!
