Term or Permanent Life Insurance,  which one is better? 
The purpose of life insurance that you are buying for. For example If  you are buying life insurance to protect a mortgage, so as in the event of  untimely death family behind does not have to bear the burden of mortgage payments  then a term policy for the duration of mortgage would be a better option where  you can cover the risk with small monthly premium and if the purpose of  life insurance is to pay final expenses, probate taxes, capital gain taxes and  other related fees a permanent insurance is better option as you know for sure  one day these funds would be required for the intended purpose so permanent  policy would pay a lum sum benefit for sure one day when the time comes and  will never run out on you even if you live to age of 115. 
Term Insurance offers low-cost protection for a temporary period, say 10, 15, 20, 25, 30, 35  years. But the cost rise many fold at renewal. For example a 40 year old male  non-smoker can take out $100,000 of term-20 coverage with a monthly premium of $28.42  however, when it comes for renewal premiums jump to $102.45 a month. 
Uses of Term Life Insurance: cover short term risk for responsibilities like mortgage,  line of credit, or business loan.
Permanent  insurance have higher initial premiums than  term policies to begin with, however generally it provides a level cost or paid  up options and lifetime financial protection.
For same example 40-year-old male  non-smoker can get $100,000 of 20-pay whole life coverage with Empire Life for  $77.10 a month. The premiums are obviously much higher, but rather than the  plan renewing in 20 years it is then paid up. 
Uses of permanent Life Insurance: cover responsibilities like Funeral  expenses, legacy to family, Probate taxes, Capital gain taxes and other Estate  fees.
