Suede is harder to care for but looks 1000 times better IMO. If you're driving every day and expect some bad weather on occasion though, get the vinyl. ESPECIALLY on kick panels. Get water on suede and you'll have a spot forever.
i recently had my headliner and pillars all covered in suede very nice looking but extremely hard to stretch over things im not sure about real suede though that may stretch a little better but its way more expensive, i would say for the kick panels do vinyl, and for the box do suede and then do suede inserts in the seats it looks really nice
