My first drill was a Bosch 14,4V, which suited my needs for a good, long time, until I started doing some actual work with it.
Spoiler: it worked about as well as my wrist - aka, using a screwdriver turned those 140mm's just as deep. And neither all the way.
Then I tried a Bosch Green 18V, which didn't perform much better, and I shortly after got a Makita 18V as I had projects I actually wanted to do.
Makita did the job, but local availability was nothing to write home about. Same with Metabo and Milwaukee, which were up for consideration as the one brand to stick to. Bosch Blue was also an option in terms of availability, along with Dewalt, but given the price of Bosch Blue...I went with Dewalt.
Sold the Makita and still trying, 3 years later, to get rid of the Bosch Greens...
And now I have quite the collection of Dewalt-tools, which not failed me even once yet.
DCF601 - driver for the smaller screws (0-40mm) (12V)
DCD796 - drill/driver for the medium screws (40-80mm) (18V)
DCD991 - drill/driver for the longer screws (80-140mm) (18V)
DCF899 - impact wrench for anything that needs to be driven in or out, regardless of length (18V)
Plus some corded tools (jigsaw, square and orbital sander, mitre saw and angle grinders) from Dewalt, Black & Decker, Metabo and Hikoki.
Got 2x 2 Ah (12V) and 2x 5Ah regular batteries, plus a 1,7 Ah powerstack, and the included DCB113 and DCB115 chargers.
Accessories includes several DT7508 1/2" square to 1/4" Hex and DW2547 1/4" Hex to 1/2" square adapters, along with several DT70734T impact ready bit sets, and some Bahco 7806 impact sockets. For cases, I find the Makita MacPak series to be brilliant (MUCH better than Dewalt's T-stack!), with the suitable inserts.
I'm only using the tools for sporadic hobby projects, and the longevity of the batteries just sitting there is a worry.
But if money was no object, I would have gone with the M18 Milwaukee. Their lineup seems much better than Dewalt's, but as a hobby user, I cannot justify the extra cost.
