Put another way, if the theoretical SL2 and M2 both had a dual pixel (D70 type) sensor and the same price, and you want small - which do you go for?
You may be over-thinking this. Within your parameters, the choice is easy: Choose whichever form factor you feel most comfortable using.
As I and others have said before, there is no "wrong" choice. If you want a true small "pocketable" APS-C camera and the rear display works for you, go for the M. On the other hand, if you prefer the layout of a dSLR and an optical viewfinder, get the SL1. The trick is making an honest assessment of what features and specifications are most important to you before you make a purchase.
In your premise above, cost was not factored in because you assumed the M and SL1 cost the same. In reality, they probably won't cost the same so cost will be one factor among many to consider when making a choice. How important cost will be in the spectrum of factors to consider is up to the individual. For me, cost is less of a factor than, say, ergonomics or image quality. I would rather spend a bit more and get improved IQ or ergonomics than spend less and have inferior IQ or ergonomics. Of course, others may feel differently, and that's perfectly fine. Canon offers two choices here that are both good. Which one you choose is totally up to you.
