iTunes is terrible, but you don't have to use it – I got my MBP at Xmas 2014 and still haven't accepted the iTunes EULA.
EDIT I would add that at least with adb its not the only option. Android is a reasonably open and flexible and open experience and there are lots of different ways you can manage your device. The iPhone for better or worse is locked down, the least Apple could do is provide something better than the lousy piece of crap that is iTunes.
You'll need iTunes the same way as you need adb. You don't.
Also, iTunes is not a "lousy piece of crap".
I commend you on your loyalty.
