I dunno, impact driver has changed my life, MASSIVELY reduced the number of chewed bits and rounded out screws vs using a regular drill/driver combo type, much less strain on body if using for hours in a day, get one with power settings, lowest is often enough, gives you lots of control without having to 'adjust' the finger trigger as daft as that sounds it is a help.
Yes, ability to pile drive massive huge fixings into just about anything if you turn the power up.
Still controllable though, i'm on an M18 brushless job (gen 3 or 4 whatever came out last year) and have no problems getting bugles in and not through plasterboard.
Last night whacked some 2x8 framing together for a shower pan, 100-150mm large size screws all round. 25-30 of them took around 3 minutes to sink them all perfectly with zero slips.

I would say though, unless your doing big jobs, the dewalt/makita/milwaukee brushless 12v ranges are just fine, much lighter to use, amazingly powerful for their size and weight, rugged enough for keen DIYer to actual tradee (many of my mates are on dewalt and makita 12v ranges for 85% of their work). Lifting an M18 impact + 5.0 (or larger) battery around all day is not the lightest, a 3.0 HO battery would be my choice if I was to do it again. 5.0 battery does last a full days work on these things unless you are a framer.

Its not like 15 years ago where you'd have a literal army of nicad and nimh batteries beeping away on chargers in a row and having to go and swap them to the next in line every 15 to 20 minutes.
