Bit late to this - hope it's still valid.
Blue Bosch 2-speed hammer drill- bulletproof old Swiss-made lump of a thing that's now permanently attached to an angle drive for joist holing - 9
Green Bosch - nearly bulletproof, at least the ones I had only broke after many years of intensive abuse - 8
Makita 7.2V cordless - utterly toy-like in appearance, but the appearance is deceptive; these things will go on and on and on, drilling and screwing all day long. Bit slow, but they get there - 8
Makita 14.4V cordless - depends on end of the market - the pro-grade ones are fantastic, the Marathon motors allied with decent NiMh batteries make an impressive combination - 8
Atlas Copco (AEG) 110V SDS - unburstable - 9
Makita 240V SDS - so far, unburstable - 8
Makita circ saw - done everything I've asked of it for 20 years - 9
Bosch 240V SDS-Max drill/breaker - heavy sod but just keeps working - the swivel lock on the tool holder has bust, though, so that's a 7.
Bosch 12V SDS - keeps on going and going, can't break it but the batteries would make your eyes bleed. Now using Makita batteries - for reliability it deserves a 9 though.
Aldi 14.4V drill/driver - hasn't broken yet, but it will and the battery is utter crap; a throwaway tool - 3
DeWalt 110V jigsaw - so nice to use, just works and produces reliable, predictable cuts - 9
Aldi 240V recip saw - hasn't broken yet, been in use a couple of years, feels ok to use and perhaps might be ok - 4
AEG 110V drill/breaker - a bit light compared to the Bosch breaker and has a tendency to break tools at the neck - so a 6 for that. Electrically, all it ever needed was new brushes.
Looking at the list, I see the majority of the ones I use most are Makita and that's simply because I found I could rely on them to just work and get the work done without spending a fortune. I also found that buying used pro-grade tools that haven't done a million hours can really pay off if you have some part of the kit already - like batteries and chargers from another application.
