Depends what your price range is. Topps 5 star and Panani National Treasures are the two top end items. For those, I have think it's better to buy individual cards or get involved in box breaks for specific teams / players you collect over purchasing the boxes yourself. Topps Inception is nice as well for a much more reasonable price (I actually have 6 boxes of these here right now if you're interested). Bowman and Panani are OK as well. Personally, I would avoid Press Pass and Sage, but that's just me. As a general rule of thumb, I always say buy the nicest cards that you can afford and try to only get numbered cards, autos, and patches, the others are basically worthless.
