IMO it depends if you can feather them down well. If you can loaded seem to cast better for me but you risk them diving deep and settling slowly when you get it slightly wrong.
Unloaded seem to settle faster and amke a better splash but don’t cast as well so when you are getting instant bites its unloaded for me.
I have just started using and been well impressed with the Steve Mayo adapters, not cheap but found they are a good balance between the two options – maybe one day I’ll have the confidence to just carry one type!! Top tip though you need to glue the adapters below 3SSG, stops you coming back with adapter and no float!
