Exactly, what are we comparing? Bridges?
The Schaller Lockmeister is a perfect clone of the "Original" Floyd Rose, which they also produce. Can't go wrong with it for a locking trem.
Schaller's two-point non-locking trems are nicely finished, solid and work great.
Wilkinson products come in a range from budget to premium. The Wilkinson bridges made by Gotoh are among the best bridges available anywhere and have a great range of adjustment.
Wilkinson tuners, however, are only available in the budget option and are nowhere near as nice as the German-made Schaller tuners, for example.
