Bosch, Neff, Siemens and Gaggenau are all part of the same group, more than likely made in the same factory with the same guarantee and the same engineer will attend should you need it.
The Neff has a slightly better energy rating of E than the Bosch F and it’s a couple of decibells quieter than the Bosch.
I am not going to bore you on pricing structures etc but Bosch will always be cheaper than the Neff counterparts. Neff will also be a higher price due to the name and supposed kitchen specialist tag they have.
As an aside do you realise these are fixed hinged machines? There are two different hinge types on integrated fridge freezers fixed and sliding they are not directly interchangeable but can be sorted by a kitchen fitter.
