I (clumsy European) strongly prefer liquids as they completely avoid the hassle with mixing and undissolved residues in the bath. Also, if the volume in the bottle of concentrate is as advertised, partial mixing is much easier with liquid concentrate than with powder.

It may be simply shipping cost which causes dev manufacturers to sell powder instead of liquid concentrate overseas ...
