It might just be a matter of education and familiarity. Having tried Kitely, I personally feel that all their regions are "there" there, just that it might take a few seconds longer to teleport to some of them.
And while I have my own grid, I would DEFINITELY consider using another provider for a personal residential region.
For example, if another grid offered me a free, on-demand region -- even if it was with a low prim allowance and only five or 10 avatars able to visit at once -- I would take it, as long as they offered OAR (or filtered OAR) downloads.
Meanwhile, my current plan is to use my free Kitely region as my "residential" home once they turn hypergrid on. I'm past my six free hours (I've had my account there since the grid first opened!) but at 20 cents per hour, I can easily pick up the tab, especially since I don't expect to be using it that much.
