I just found now the time to listen to the 2nd version , and I agree with Vgonis, I prefer the 1st version.
the mimimal drum click fits more to the song IMHO, and the guitar sound/mix is more "relevant" in the 1st version. It has this JJ cale flavour, that I missed a bit in the 2nd version.
I agree with you though that real drums are most of a time better than a drum machine, but in this case, I prefer the machine

there are some examples where a drum machine fits more than real drums. It can make a special ambiance like e.g. on
in the air tonight (before the real drums comes in)
Another example : I like very much the instrumental on
Golden demos (the melody that later ended up on
behind with the rent) : a drum machine, some synths and Mark's guitar, great atmopshere
as for mixing, I 'm not sure I'm the right person to give advices.
My recordings were all made through the Tonelab ST (used as a soundcard), no amps no mics, even the drums were trigged ("real" drums, with real drumhead but trigged, with no acoustic sound).
And I use headphones for mixing.
As for playing on a phone, I'd say it depends very much on the headphones.
the iPhone has a very low level , and the headphones are quite bad IMO, so I changed for better headphones to get more bass, more presence
