For GNOME, the Tiling Shell extension works well for me. I've also used, and liked, gTile. Of course, with an extension there's always the danger that it will break between releases and/or the developer will get bored and stop maintaining it. The nice thing about Tiling Shell is that it's not all-or-nothing tiling. It's tiling when I want it, otherwise just "normal". COSMIC Desktop is promising, but has a lot of maturing to do.
