Essentially the same story with different cast. Acting is roughly comparable as well.
Loco Motive Kissing Butterfly (1) is longer with more details from the source material. Jing Mo Xia Tian (2) cuts out some aspects but story is still complete enough. (1) has a more bittersweet vibe than (2) imo, but specific plot differences don't really come to mind (except where FL is when ML commits the act that puts him in jail).
Can watch both of you are a particular fan of any of the cast members or if you really want to kill time.

If you prefer: Extreme push-pull tragic romance tension; Female protagonist's growth line of solitary courage in pursuing love; Painful redemption aesthetics >> Recommend "Motorcycle Kisses Butterfly"
If you prefer: High-profile CP and exquisite visuals; Mutual secret love's heart-throbbing attraction; Gentle healing sweet pet tone >> Recommend "Jing Mo Xia Tian"
