Leading (or check-raising) is better because now you are letting him define his odds (if he is on a draw). He can easily have a flush draw here and semi-bluff. So make him pay, but if you meet to much resistance and he is tight, slow down and check/call or check/fold after the river depending on your read.

The river is a bad card for you, so be careful. You are behind a lot of cards that a player at the button at low stakes can call a preflop raise with (KT, AT, QJ, TT etc). I can't say you river bet is bad. It's a decent value bet, so if he raises you can be pretty sure you are behind, and, at NL25, players can even call and pay you of with a king.
