Just a quick question about tokens vs subscription

So in terms of using chatgpt to write stuff for me, if I’m paying the €20 subscription fee, there’s no actual limit in regards to the number of characters / words per day? … Basically, I’ll just be using it to write (at max) 4 articles or blog posts a day, with a maximum of say, 2,000 words per post & I’m trying to work out the cheapest option, tokens or monthly subscription?
