Beware of some power tool brands. Makita and Maktec are the same looking tool, made on the same factory and using similar looking parts. Aside from the screws though they are totally different, the one is cheaped out to the max, using inferior parts and things like bushes instead of bearings, smaller batteries with a packing piece and so on. Applies ot the corded and cordless tools, and they also make house branded tools as well, increasing the confusion.
However, buying quality tools is a good investment, as they tend to last longer, and power tools with a cord have a big advantage of being able to store for a year, pull out of the box ( with the appropriate corrosion protection on them) and plug in and use, so that is a plus. Cordless has convenience, no power cord to snag, you can use them up a ladder or in a roof, you can drive to the place to use them even if there is no power there and such for convenience. However when that battery goes dead you are stopped till it charges, and there you either do something that does not need power or have an impromptu lunch break.
The construction and trade use corded tools for the most part, mainly because I have yet to meed a SDS cordless that will drill a 75mm core through a 150mm masonry wall, or through 330mm of reinforced concrete with a single battery. OK the Bosch is 9kg with the drill bit, but a lot lighter than the older Bosch I used before, which is 25kg excluding anything, and which is quite capable of breaking bones, but it will drill a 110mm hole no problem provided you can hold it the time without you failing.
Driving screws into drywall the cordless is no issue, will do them all day, and charge up a bit over lunch for the afternoon, but if you are doing things like hanging lights, running cable or conduit then the corded one will win out.
Yes I have both, and they both have a place, but there is nothing to replace a generator and a corded power tool for high power output. I have yet to see a cordless inverter welder, though I love the inverter, as it is so much easier to carry up a ladder over a buzz box.
