Lexus GS450h (F). Experiences of owners / buying?

I’m thinking of buying a Lexus GS450h, or a GS in general. The 450h didn’t really prevail in Europe, there are hardly any. Are there owners who can share their experiences? I’ve already had Lexus and always when I’m in Dubai I’m mainly sitting in Lexus ES300h, because that’s the Uber Comfort model there and it’s just a pleasant car, in almost every respect. Quiet, good seats, good city consumption, everything that makes a Lexus so special. Ic h had an IS300h myself, but I never drove the drive of the 450h myself. How can the difference be described? I would expect a very quiet car at the GS450h, can I confirm this from practice?
