From my experience with several Keyreative sets that I've had, the clarity of their dyesub and reverse dyesub edges between legend and base colour of keycap has been really good compared to some of the other PBT dyesub manufacturers. The biggest gripes I've heard with Keyreative is their super long manufacturing times (they're still clearing a backlog of GB orders), and alignment of legends (which has gradually improved given designer's demands/concerns... (although it is a question if this is sustained over a mass order and their QC). In fact, they've shifted some of their sets in production from dyesub to PBT doubleshot to assist with that issue.
