What tileset from the original levels is the best in your opinion? Since there are always 2 or 3 tilesets of the same one (labrat1, labrat1n, labrat3) that are diffirent only by color or some small details (e.g. one version has trigger blocks, the other doesn't) I counted all versions of a tileset into 1 set.

I guess I can choose too ;p

Also please write what tileset from other version.
