Berkley Fishing Gulp

What is the difference between berkley power bait and gulp fishing lure?
Which one is better for fishing in river or estuary?
I mean between berkley power bait and berkley gulp.
Gulp! tends to be a little stronger scented so it gets a few more bites, but it dries out pretty fast.
Powerbait will get strikes too, thought maybe not quite as many as Gulp, but it lasts a LOT longer.
I tend to steer toward powerbait unless I see something in the gulp line that I really like and powerbait doesn't have the same lure.
I hope this answered your question. Tight lines!!
