Everyone is different. I don't spend a great deal of time and energy on these surveys, just knocking off a few when I have some down time and they are generally offering me surveys in the range of at least 4-5 rewards points per survey. I earn enough points each month to redeem for United miles at the rate of 2,000 miles/month or 24,000/year, plus a few $50 Apple gift cards here and there. I consider that a reasonable return on my time investment.
