If you are Plat, you may expect better perks at Kobe Sheraton. Check-in at Towers Lounge, Towers floor, FULL breakfast, etc. But the biggest advantage is easy-access by "limousine bus." It takes less than an hour and it's door-to door.

At Westin Osaka, you may expect corner sweet room, breakfast at Executive lounge but the lounge is really small... Buss access to Westin is once a day. Yes, once a day! ridiculous.
