Berkley Gulp Alive Minnows can't be beat. In my opinion. Pop
I will say personally that I have used Berkley Gulp Alive minnows myself while a fishing partner in the boat was using live minnows and I have caught more fish at times as well.
So because someone prefers to use a bait that is not alive does not mean that bait is automatically going to catch more or fewer fish than active live bait at that time, in that place.
I may have that same opinion if I have not done it myself on more than one occasion. I do find that the Berkley gulp minnows can be very effective from using them.
The biggest advantage in my opinion is not having to worry about keeping the Berkley minnows alive and they do catch fish.

I was on a trip this summer (very hot) that I couldn't buy a bite with jigs on day one. Day 2 took a couple dozen minners just in case. Same scenario on day 2 but I switched to live minners. They were killing it. I started to run low on live minners and fished recycled minners that were dead and loose in my net. The dead ones was still out fishing my jigs.
Don't get me wrong I prefer and typically use jigs/plastic but I really like catching fish and will use all the bait options in my tackle box to be successful. I've got a jar of the pickled minners and berkley gulp minners in my box for the just in case I got nothin else to throw.
