I recommend the Lifetime just because it’s convenient at this juncture (with the sale being current).
Otherwise, you’ll spend much more than that amount and/or quit.
A little over a year ago, I paid for monthly in August/September until the lifetime sale, and then picked that up. If I had had a lesser subscription, real life would have forced me to abandon the site altogether around August or Septemberthis year, but I’ve stuck with it…
The other question is on how YOU want to use the $ in your bank account, of course.
