I can't say about other solutions, but JOSM has several developers working on it with regular releases (monthly).

comment Quickly create contour polygons from cost points using OSS for web app
I read that, but the problem with my data is that the distance between points varies significantly, maybe between a meter and 50 meters or more. I haven't yet found a value that gives good results. Maybe I should find out what method the QGIS contour plugin uses.

Thanks for the suggestion, I've been playing with v.surf.bspline for a bit, but am having trouble getting sensible results. I think I need to better understand the parameters; I've varied the spline step, which changes the results significantly, but I haven't figured out what's the "right" number to use yet.
