Hi,the choice of cordless anything,is always down to several factors...cost,use,personal choice,and yes,even fashion.
There is also a big trend on most youtube tutorials,for doing everything,with a battery tool...you see chopsaws,table saws with big double battery packs....and a socket outlet,2 meters behind it ? - always choose the appropriate tool,for the job.
I can rate the Hikoki,,Milwaukee and Hilti gear,probably putting Hilti in the lead for engineered quality,but not on every tool they make.
Pick the tool for you and your job...i went to visit a pal who was doing a load of electrical/coms work in an office,and he had invested heavily in Milwaukee kit....to "obviate extension leads everywhere..." he still had the leads,as his lads still needed heat guns and battery chargers,so...
And lastly,ignoring theft and abuse,buying quality gear,is always the best policy. I have an old Hilti 14v combi,which i keep,as it has 3 speeds,Hi being 2400rpm,perfect for burrs,mini-wheels,small bits,etc.
It can still do a 20mm hole through 1" steel plate,with a Starrett holesaw,on a single 3.3Ah battery,
