Landa with a full Sky support team could easily win a grand tour, particularly a hillier, TT light version. Movistar have a strong support team too, and perhaps have realised that Quintana might be good for only one grand tour a year, so some GTs open for him to lead.
Also Spanish leader of a Spanish team, probably an easy choice. I expect that would offer greater endorsements and sponsorship money for his personal income, compared to being a leader at Sky, even with a larger salary.
