I have unlimited and I am taking 35 days off this year. Not including the 9 days paid holidays I get. I took around 30 last year and had 10 paid holidays. My previous company gave us 24 days PTO, no paid holidays (we could choose which holidays we wanted to take off but we'd have to use PTO). At that company I consistently took off 30+ days total.
I am in the US, both are US companies. I could not handle having less than 40 days off a year and make it clear before hiring that I am going to take plenty of time off. Yes I am productive, no I do not work long hours (~35 a week at both places)
