Cordless complicates matters in that you really want to choose the right battery set and charger, rather than the individual tool you currently need. Reason is almost all the popular cordless makers can supply a tool only option for almost all eventualities. From circular saws to torches, and impact wrenches and jig saws. So its the battery set that gives you the best options that you need to seek out for your needs.
Having said that, if your looking at a workshop only cordless impact wrench, then the snap off range knocks the spots of everything else when it comes to impact wrenches. The daddy. If looking at wheel bolts and high torque figures especially.
However, get some opinions on decent corded tools as they are cheaper.
I suspect though, for you personally, a good cordless tool would be very handy indeed, young bear
Ime, a progressive trigger is a must. Btw.
