Hi there, thanks for the question!
These tilesets all came before the Super Pixel tileset series, so some will fit with them better than others. My style was evolving at the time, so the Super Pixel tilesets are generally more flexible for level design. Other than that the most notable difference is probably that the Super Pixel tilesets have a dark outline around the terrain, which was less common in my earlier tilesets.
I think the Dagogum Cavern tileset, the Molten Foundry tileset, and the Derelict Spacecraft tileset would probably fit with them the best style-wise.
