Some strange comments on here regarding Bosch. We are talking Bosch Blue and not DIY Green?
I have owned my Bosch SDS for as long as I can remember (15 years +) along with my 10.8 drill driver, which is the mutts for kitchen fitting. I continued with the SDS even after my old man passed down his Hilti's. Also owned the Bosch GCM12 which was the only the really big saw around at the time locally for me , and before the Kapex and others came out. Have also owned the Metabo kgs 305 & 255., the 305 being a beauty and very quiet.
With Festool have owned the T55, the 65mm planner and jigsaw. With the first use of the Festool tools and fitting front framed bedrooms, and as a guess I would have estimated we saved at least a days labour for two chippy's ripping down panels etc. Fanatstic tools and well worth the premium IMO. With the jigsaw and festool blades and using it to cut out a sink it's probably the only blade which didn't burn out and undercut. Most worktops are filled with crap to give them weight and are a pain for jigsaw blades.
With tools I allways found some brands were better than others for certain things, so I never committed to one brand.
For me, I had Festooll for ripping down and planing on kitchens and bedrooms then using a Bosch SDS for drilling the pilots for walls and Bosch 10.8 for fixing the screws.
For general carpentry and heavier work I had Panasonic & Makita Drills for things like decking, loved my Impact driver, makes driving in long screws, bolts etc........ so easy.
For ripping up tiles etc............ I had a Milwaukee, an excellent tool.
Routering I had a Dewalt 626?. Trend dust extractor.
Nobex Champion mitre saw for fixing beading after laminate flooring when the customers wouldn't pay for new skirting. Paslode IM200 for fixing the 18g nails.
For me I wouldn't get hung up about 18 volt for your uses I would concentrate on the batteries ampage, which for me was more important.
The best cordless drills / twin set I have ever owned have been Panasonic, people in the know, know these are the dogs danglies.
If Makita keep away from the red battery ones if you plan on some heavy work, their for DIY like Bosch green.
