Mini pump with or without a hose

Hello all,
I am about to replace my mini pump with one that I would be able to
attach to the frame, and that would, hopefully, be more efficient.
While the old-fashioned mini pumps have a flexible hose, some of the
more recent ones do not. I have the impression that a flexible hose is
useful to avoid damaging the valve, but I wonder if this does not
degrades the performance (by which I mean, the ability to inflate a tire
to a correct pressure without excessive effort).
Do you have any advice on this matter?
Bicycly yours,

A hose adds volume, which is significant with mini pumps. With the same stroke and diameter of the piston this results in less pressure. Another problem I saw in practice is that the inner of the valve gets unscrewed while unscrewing the hose after inflating. If I would use a mini pump I would choose for a non hose one and practice on my technique but I gave up on minipumps and use CO2 cartridges now. YMMV.
