Buckets - Late model extended cab Ford Ranger or T-Bird (same seats). The seats have longer slides, passenger side tips up for rear access (I believe). Get them with a console if possible, it'll all fit as one unit. Pros - Seat covers are readily available. You can get neoprene covers, fabric, you name it and they can all be found on the shelf at your local Wal-Mart. Some even say "FORD"! Very comfy to, some with an extended support for your legs and adjustable lumbar. Power seats are out there, check the T-Bird's first.
Bench Seat - I have a 60/40 out of a late model Cheby S-10. They fit great, are quite comfy and recline way back. Look for a set out of an extended cab for same reason as above. Negative - Don't know about power seats or adj. lumbar being available. VERY hard to find quality seat covers for them and of course, it's a Cheby part on a Ford :-[
