I like to have the gps for when the route sheets go wrong (which with me, they tend to do).
I really enjoyed the 2010 DB1k, following the route sheet (from printed a4 sheets, printed in a5, double rows in my tank-bag)
So I would say, I like route sheets but the gps feels like a good safety backup (hard to step back through a route sheet if you miss a marker or a reset).
