When there are good $4 cantrips on the board (e.g. Caravan, Tournament, Ironmonger), Remodel can be a strong opening. Lacking that, I'd rather have Remake. When you don't trash it, Redistrict should be weaker than Remake or Develop for trashing Estates (as befits its $2 price tag), but at least when you have a hand of [Copper, Copper, Copper, Estate, Redistrict], you can Redistrict the Estate and still buy a $3 card that turn. So it doesn't kill your current turn as badly as Remake tends to do.
To elaborate, there are lots of better ways than Remodel to remove Estates from your deck. Lacking any of them, Remodel can be a nice choice since early removal of Estates tends to be a strong play.
