Hi rojaros guitar,
both sound good recorders to me, I think they fairly represent the recorded sound, whether more 'naily' or warmer ( are you suddenly switching to apoyando or going nearer the hole for a few seconds?), and it all sounds pretty similar as you'd expect given that you use the same microphone (what microphone is it by the way?). I guess the only difference could be in the impedance matching with the microphone, and any 'character' that the recorder's preamp might add, effects that seem to be rather subtle for me in this case (though I am listening through computer speakers!).
