grandis ako, dami kasi sobra fort sa daan, everybody has one. but if you need high ground clearance + offroad capability + diesel engine e di fort. if none of those 3 aspects you want or need then the grandis is your best choice.
Between the two, I'd go for the Grandis... it looks more gorgeous to me (especially the LED tail lamp) and if a refreshing break from the sea of Fortuners that is prowling our streets.
