Stuck between two flight options, need help

I will be flying to Japan in a few months, with a layover in SFO.

I have been given two options:

– SFO to HND flying with United Airlines (Economy)

– SFO to NRT flying with ANA Airlines (also Economy)

Both are for the same price, I will be staying near Shin-Okubo station, so there is a 10-15 minutes difference between HND and NRT arriving to Shin-Okubo station (being NRT the furthest obviously)

For those who have traveled with both airlines, is it worth the extra 15 minutes and the price of a Skyliner ticket to fly with ANA, or is it too overrated and United is the better option since it will arrived to HND.

Thank you in advance.
