I haven't looked at the new Sienna, but I'd say that the Honda Odyssey has been the gold standard/no brainer purchase in this category for more than a decade. I owned a 2002 Dodge Grand Caravan and a 2008 Odyssey, the difference in quality was mind-boggling. After five years, the Caravan was a clapped-out mess, everything in it looked about 100 years old and stuff was starting to fall off. By contrast, after 10 years the Odyssey was still in very good shape, obviously well-used, but solid and reliable. If I needed to buy a minivan by 5pm today, I'd feel 100% comfortable going to the Honda dealership and picking my preferred Odyssey, without even looking at other brands. Next in line to look at would be the Toyota Sienna and then the Kia, which offers solid price/performance, but IMHO it's a significant drop from Honda/Toyota level.
