As far as better data coverage goes, that's a tough one to answer. Have
you looked at the coverage maps for each carrier? I know they're
probably not the most accurate, but each should give you a sense for
whate cities and areas are covered, and you can make a judgement from
there. The easy answer though is that both services should cover every
major metropolitan area quite well with data capability.
As far as roaming goes: Sprint data services do NOT work when roaming
off the Sprint network. That said, I don't believe EDGE services work
either when roaming off Cingular's or AT&T's network, though the much
slower GPRS service most likely does work while roaming.

GPRS like 1xRTT on CDMA can work on any carrier/network you roam on that
supports it. The problem is most roaming providers don't allow data usage
because of cost and management(not that it isn't possible). When I had
Cingular, and granted this was before the big merge to GSM, their data
services only worked via their native digital network. There are AMPS data
services that work almost everywhere but that is usually for speciality
items, such as autonomous reporting devices, where maximum usable coverage
area is more important then bandwidth. Such services are not normally a
setup given to a consumer unless it is specifically asked for at a carrier
who supports it.

I believe that Verizon data services will also only function when on the
Verizon network. I have had both Verizon and Sprint and prefer Srint Vision
as you can get unlimited Vision for $10. Verizon does not offer an unlimited
data plan except for laptops.

While you can cheat and do some laptop data over the unlimited vision, many
people have gotten called on it. If you check your e-mail every now and
then, you'll probably be fine. If you choose to substitute this data
service for your home DSL line, watch out.
Roaming is the big issue in my mind. Sprint's data coverage is very good.
They are about to go to EVDO which will move them ahead of Cingular for a
year or two until Cingular gets one of its two 3g technologies running at
full speed.
Does your fleet enter Canada? You can roam in Canada with Cingular. Sprint
has no data coverage up there. I'm not sure whether you can get Edge now or
not. ATT (now part of Cingular's) historic connections with Rogers (the
owner of the two GSM carriers in Canada) means better roaming up there.

I have a Sprint cell phone and a Sprint laptop card in my laptop. The laptop
is on an unlimited Sprint data plan for $80/month and it works very well in
the US.
