Help a brother out with some retirement planning advice

So, I’m looking at jumping to a position with different company. Same job but much better environment/atmosphere better opportunities for advancement etc.

Pay will be slightly better ($5 an hour more) but I’ll be giving up 2% 401k match and new company has no annuity/pension benefit.

My current employer offers 8% match and annuity formula below.

11% of highest 5 year average X years of service before age 60. 32 years of service at age 55 would put me at around $420k

If I make the jump the idea is to apply the extra earnings to maxing out a Roth IRA for the next 28 years along with maxing 401k every year. How would this compare to the annuity at retirement age
