Capture Quests give more money, that's already in the main quest. Both have subquests so there's no difference if you count subquests in or not.

Capturing the monster gives the items you would've carved from the monster (sometimes less) if you killed it. But the materials you get have a higher probability to be the rare ones. For example the Rathalos Ruby can be get in a 4% percentage when you break everything and cut everything and carve it. But the capturing increases this percentage to 8% what means that Capturing a monster is more rewarding. (Tell me if those numbers are false, just made that from memory and I could've mixed up something.)

And the costs for shock/pitfall traps and tranqs aren't relevant as you get them in every Capture Quest. When you capture a monster in a killing quest those things aren't that expensive either.

When you get a Ruby/Jewel/Gem/Sapphire and sell it you have always the most rewarding way. lol

And as you can sell those with a capturing twice (Rathalos Ruby) as often as you would sell with a kill means you'll always have percentagely more money after the capturing.
