Your choice depends on which flooring you really want. Our experience w/ self leveling wasn't all it was cracked up to be. Apparently we aren't the only people who have had this issue. We've always had acid stain floors and really enjoyed them.
After we took down walls and removed tile we were hoping to just throw down self leveling microtopping and acid stain. Nothing is simple. In our case we also had cutback/black mastic stuff that needed to come off. Maybe we used the wrong stuff. We used the Mapei Planipatch and the Mapei's Novoplan 2. Level does not mean smooth. We had to sand it down.
I needed to move the project along. So we just painted and left it with just the planipatch in some areas. It's a process to get it right. We didn't acid stain.
If we weren't in a flood prone area we would have gone for the engineered floating floor. It's quick, easy and satisfying. It is also warmer than concrete flooring, and you guys get snow. We don't - sun sun sun sun - yuck.
The acid stain got us a ton of complements. We wish that we could have finished the project, but we have about 1 more year worth of work to finish rebuilding the hurricane house. I hope this helps w/ your decision making.
