I have both I prefer my Seiko Kintec over the Cizten.
Yes, think Citizen Eco Drive are by far the better, and this for two reasons: One, because their Solar system is more advanced than the Seiko one and so, they do not discharge so easily, accumulating more energy; secondly, because Seiko already had a big failure with their awful kinetic energy, which made the watch to have to be constantly in your wrist to be moving for if not it got discharged. That failure on the Seiko side made it an unreliable trademark for me. They moved into manufacture solar powered watches, afterwards, but do not think will ever again buy a Seiko after that nasty experience. Have to say am the proud owner of two stylish blue dial Citizens (one of them radio controlled too), and they are extremely precise and robust watches. Really, Citizen is an excellent, reliable trademark.I started off with a Seiko, switched to a citizen eco-drive, much nicer IMO. Both good brands, i just prefer citizen's "flashy" style more.
