I would second the above. I am a DIYer but doing up a whole house so I bought a £400 DeWalt twin pack brushless 18v drill/driver and impact driver.
I reckon if you’re just doing the odd job around the house a quality cordless drill driver and leave it at that. The impact driver comes into its own if you have to do loads of screws, or screw big screws in repeatedly. The way they work means the screw heads don’t strip and they have loads more torque so can put huge screws in without damaging the screw head.
Mine has 3 settings the lowest of which was great for putting plasterboard screws in.
You also don’t have to keep swapping over from drill to screwdriver bit which is nice, and the unit is smaller so you can get it in places the drill/driver won’t go.
