Hi!
Right angle chuck, glad you pointed that out.

Yes, it's missing in my comparison. Why? I have used it a couple of times and it's great, and I wouldn't want to miss it now that I have it - but I have yet to come across something where it's the only option because of size/space.
I often just grab a larger extension and go with that. If you need that attachment constantly, yes, the Festool wins.

Bosch does not offer a right angle chuck for the 10.8/12V line-up as of now, only a heavier/bulkier one for the rather new 18V GSR EC FC2 model. But that is a lot bulkier because it's a "real" drilling chuck. And not everyone is really happy with that solution from what I know... .
Kind regards,
Oliver
