I think it is just down to what you are used to skating, more than anything.
Same Indy trucks on a mellow board, everything works for me, then tried on a steeper board - ghost pop and had to change everything for how I skated, but back on a more mellow board, I felt like everything worked as it should for me.
If you are used to lower trucks, sure things are going to be weird, but that is also why I prefer to put DIY 2mm rubber risers under Thunder trucks to bring them up to a more "normal" height for what I prefer.
Everyone has their own preferences, so there is no right or wrong answer to which product is best overall, only what is best for each person, depending on what they like.
How a truck turns, how quickly or slowly it turns and other performance issues can be down to quite a few things, but the easiest thing to change with a set of trucks is in the bushings department, which is why I prefer a slightly harder bushing that is not tightened down as much, over a taller, softer more mushy bushing, that even if tightened down a bit, will more likely cause more issues with not being able to bounce back as quickly but will still turn a little too much, which would cause the "twitchy" feeling that some trucks give.
The most difficult thing is getting the right bushings, or the right mix of bushings, given some people prefer to mix and match hardness options, or shapes and sizes of bushings too.
This also contributes to kingpin / hanger clearance, wheelbite and can affect performance too, because some bushings that do not perform as they should, ie they do not bounce back to centre, will usually cause more problems for the skater in the long run.
Just a few things to consider anyway.
