which 401k plan sounds better

I am in the process of comparing two job offers. I need SOME help understanding 401k terms and compare which plan is better.

 

company A : SALARY: 90K

Company A match 80% for the first 2% to 5% of pre-tax, roth 401k or after tax contribution, has a five years vesting period.

employee also receive an annual contribution of 5% of eligible earnings.

 

Company B: Salary 120k

company B will make a contribution to an employee's account of 5% of an employee's compensation for the calendar year, plus an additional 8% of the amount of that employee's compensation that exceeds the social security taxable wage base.

since I am not very familiar with those financial terms...which plan sounds better?

 

thanks for the help!!!
