Looking at two job offers

Hey everyone, so I'm looking at two job offers and I know which way I'm leaning but I thought I'd come here for some additional advice.

Job A: $33/ hr, $1500 sign on bonus, currently 100% 401k match up to the maximum allowed contribution. This is a growing company and I don't expect the 401k match to stay at 100% but they have matched at 90% in the past.

Job B: $37/ hr, no sign on bonus, typical 4% match of 401k contribution.

All other benefits between the two are basically the same. Vacation, health insurance, etc.

I'm leaning toward Job A because of the 401k match. Currently I've been contributing 15% of my paycheck so that's worth $10k a year.

This is for construction inspection in the Midwest. There will be a fair share of overtime in the summer if that's relevant.
