It all depends what you want to do with it.
1 Torque setting if used as screwdriver and reverse.
2 SDS if drilling walls
3 Rotor stop if sinking socket boxes and chiseling.
4 Extra batteries may also be required.
5 You may need to charge from 110 volt
6 You may need car charger
7 If using grinding wheels etc. SDS may mess things up as often the chuck can float back and forth.
And often the chuck with SDS models is an extra.
I used cheap drills as a screw driver and expensive one for SDS so I could give it time to cool down. Drilling 25mm holes through a wall takes a lot of power and drills get hot so we would drill so long move to other job then return when cooled. Which is best all depends what you want to do.
