You'll get a lot of different answers because there is generally no agreed-upon "ideal level" for each of the maps - it differs quite a bit depending on your swords' types, stats, and statuses (e.g. sakura fubuki), as well as your own comfort zone. For instance, a level 35 Tantou would probably perform worse than a level 16 Hotarumaru with sakura status and maxed stats on worlds 4 and above. Hard to recall, but I think my own preferred levels were generally starting around Lv20 for World 3, Lv30 for world 4, and Lv45 for world 5. You will probably find your own ideal levels by sending your swords in yourself and seeing how they do (as you can always retreat after a battle).
