There are only a few benefits of slow leveling such as convoy, plunder and sage battlefield, but I would recommend to level up to 70 as fast as possible to unlock Kage treasure and get a free draw every other day.

Also, reaching 32k in power grants you access to Itachi TI which will boost your power even further with gold ninja tools. In all, fast leveling outweighs slow leveling, those high lvl with low power usually neglect a lot of features that increase the power such as summon runes, ninja tools, refinements and rune stones.
