My reasons for doing the degree are for self-satisfaction, proffessional development and to aid a move into a different part of the aviation industry.
Which are very good reasons!
I think it's worth remembering the issues of education versus training. If you want to fix or build flying machines, which is a licenced engineer or equivalent, you need some education and a lot of training - leading to licences.
If you want to design, test or analyse aeroplanes, which is ultimately as a chartered engineer or equivalent, you need some training and a lot of education - leading to a degree, and later to IEng or CEng.
(Then both then generally require a lot of experience to make you really useful.)
If you are unclear as to the difference between education and training, imagine your daughter coming back from school and telling you that she's done sex education - you'd not be too worried. Now imagine her coming back from school and telling you she's spent the afternoon doing sex training...
The aircraft maintenance degrees on offer are, to a large extent "neither fish nor fowl", so they'll help you take either route, but much else is then (or previously) needed for it to make you properly employable.
