As a guy that put in over 100 hours into Technomamcer and played it to death, yes it is head and shoulders above anything Spiders have made before. Truly an enjoyable experience above everything else they've released. In fact, I re-download Technomamcer last night and started a new game just to see how it fairs, while theres certainly similarities, the production values, writing, in general the believability of the writing - world tie up in GreedFall is so much better, you would think a much bigger team made GreedFall and with a budget 5 times bigger than Technomamcer, too.
