This is a subject that comes up from time to time in various guises. As Rose says, everyone has a way they deal with a design, and different designs do need to be tackled in a different way than others sometimes. I suppose, for me, I follow the line of least resistance and follow form and colour, otherwise I'd make a permanent home for our un-pal,

But I work on big cross-stitch designs with 30+ colours as a regular thing. (

) However, when I'm doing hardanger, it's another ball game altogether, because there is a sequence in which the work must be done.
The back of a design is important insofar as it impinges on the front: if you have a really lumpy back, the front will probably be lumpy, too, when it comes to finishing (in frames, for example). Using loop starts or that fancy way of keeping all the threads in the front as you go along helps to make the back neat. However, I am always thankful we are mostly past the time when the back of the work was as important as the front: talk about confusing your priorities!!
