Not at all; the delta-V to those is huge compared to any number of NEAs.

Much of the velocity matching can be achieved via Martian aerobraking.
So delta V wise they're near the top of the list.

There have been some hints suggesting water within the Martian moons.
But we don't really know.

That's why I advocate a fleet of prospector probes to determine what
resources are within easy reach. Phobos and Deimos should be checked out
as well as Nereus, 1979 VA.

These are my favorite asteroids:

(these asteroids have a 1.5 year period. There are also 1_33 and 1_25
pages. some of the 1.25 year asteroids have a very low delta v.)
