When it comes to company perks and benefits, there's no better place to work than Facebook. For work-life balance, it's Starbucks.

That's according to career-data company Comparably, which surveys employees at thousands of companies on topics ranging from compensation to stress. On Monday, Comparably released two lists, ranking large U.S. companies--those with more than 500 employees--according to work-life balance and perks and benefits. Comparably founder and CEO Jason Nazar is an Inc.com columnist.

The reports are the result of informal online polls of visitors to the Comparably site, not scientific surveys. And these rankings are only the latest among several such top-employer listings from a variety of outlets whose findings span a range of companies. For example, Inc. published its own annual Best Workplaces report in May.

While Starbucks was named Comparably's best company for work-life balance and Facebook took its No. 1 slot for perks and benefits, neither company earned top recognition for both categories. Companies on both lists include Intuit, Overstock.com, Expedia Group, Costco, Zillow, and Bloomberg.

Popular benefits among respondents at the top companies include 100 percent health care coverage, dog-friendly offices, gourmet food, paid parental leave, profit-sharing bonuses, and flexible schedules.

To determine the work-life balance ranking, employees were asked these questions:

  • Are you satisfied with your work-life balance?

  • On average, how many hours do you work per day?

  • How long do you take for lunch breaks?

  • Do you feel burnt out at work?

For perks and benefits, the questions were a little more specific:

  • Are you satisfied with your benefits?

  • Do your company's benefits play a part in staying at your company?

  • How would you rate the perks your office provides?

  • What do you estimate the cash value of your benefits to be? Health care, paid time off, etc.?

  • How many paid sick and vacation days can you take per year?

Here are the top 10 companies from each list:
