Always had gas ovens before and thought they would give the best results after poor experience of old fashioned electric fan ovens that seemed to produce a lot of smoke, noise and heat but not great cooking results.
Had a new kitchen installed early in 2013 and the company that did this were big on Neff so we went along with it. I have to admit, I have been blown away by the Neff ovens, quiet, clean, great results and touch wood, reliable. One, possibly both have needed new bulbs (they are oven specific so I bought a couple as spares via mail order) but otherwise haven't missed a beat despite regular use.
Hob is a big Neff induction job. Again after years of swearing by a good gas hob the induction thing has won me over completely, can't think of a single downside to a good induction system other than you might need new pans that are induction compatible.
The slide away door on the ovens is great.
