There's something about the first one that's special. It's sort of dreamlike.
I agree, I have the same impression.
I think this could be due to the "right weirdness" of the colors; just enough to make you wonder "why?" but not enough to ask "what the ...?"
Remember: The camera you have with you is always the best one for the shot.
Remember, too, that the image shot on your cellphone may not let you do with it later what you could be doing later had you used the right camera!
I agree with both: if I were to take photographs for a customer job I would certainly go with the best equipment I can own or rent.
But since I'm not a professional I indulge in gear-laziness
I must also add that, even if it's true for me that "The camera you have with you is always the best one for the shot", I noticed that shooting with film or the mobile sets me in a slightly different mindset: I'm less interested/obsessed with perfect focus/perfect exposure/no blown highlights etc. etc.
It's not better: it's just different.
