Same here, Dale. Prestas for ALL my tubes, wheelchairs AND
handcycle. Same when I was still able to ride a road bike. All my
bikes had Prestas. Twenty years of Prestas for four bikes (LOTS of
tubes & tires), no problems ever because of the valves.

Presta advantages: (1) lighter, (2) empty and fill faster, so
facilitate tire changes faster whether you're running clinchers or
sewups, (3) capable of handling higher tire pressures, (4) When was
the last time you lost a valve core out of a Presta?

Schrader advantages:

Gary: I'll grant you that Prestas can be a little tricky, but if you
ever get past your hassles with them, you'll never go back to
Schraders.

Just my opinion. I use an electric pump that plugs into the lighter
on my car. I got it at Big Lots for ten bucks. With a $2 adapter
that you can get at any pro bike shop it works fine for filling my
tires. Takes about 45 seconds to fill them to 110 psi.

In general, even if your tubes are "healthy" they'll lose up to 10
psi a week regardless of what valves you use. It's the butyl rubber
the tube's made of, not the valve.
