I rough in commercial and residential electric daily day in and day out sds are fine for what there designed for that is concrete I use a dewalt impact driver and standard drill for most everything I do except for boring large amounts of holes in wooden studs then I use Milwaukee hole hog as boring a bunch of holes with a cordless drill is to hard on it. I recommend a Dewalt 20v cordless impact driver and drill they will cost you a decent price at start up but taken care of will pay for themselves quickly the reason why I recommend the 20v is the lithium batteries,they are light and compact and they also have a belt hook so your not chasing your drill all the time. Steer clear of the 18v Dewalt as they are heavy and cumbersome and the life of the batteries is substandard
