My preference on jigs versus Texas rig is the ability to put the jig in places you can't with a Texas rig. Someone else mentioned the versatility of the jig. I'm speaking specific to the cast. You may argue that a cast with a Texas rig may end up in some of the same places. I'll argue that you can controllably cast a jig well into cover, or under a dock, skipping it like a fleeing baitfish - without changing your equipment, set up, etc
Like others here I pour my own. And I came from always fishing a texas rig. Once I researched the jig and learned how to cast it with control, I rarely use the Texas rig. Not every jig has those capabilities. Just find one that meets the standards you want and targets the fish you want to catch.
