The Myota version is considered the best (distinguishable by 3 screws in the center of the rotor, the swiss has one, and additional deco on the movement itself, the rotor is the same on both). The Myota also has a "better" logo - unfortunately in 2/3 (estimate) it´s wrongly glued on the dial or the parallel sticks at 12 - are not parallel. IF You get a well aligned one You have a slightly better rep BUT it needs luck and patience and a good TD to get one in the right conditions. Last time I checked some months ago the Myota was $65 more than the BP version with swiss ETA (that probably is Asian). As far as my knowledge the alignment issues where never so frequent with the BP-versions. Main priority imo would be to get the thinnest version (!) available and if everything is well aligned.
