It seems to be quite a lot worse than the Danish. Stockfish Nnue gives around -0.57 at depth 33 for the Danish (after 4.Bc4), while the Ryder has around -2.36 at depth 32 (in the position after 5...Qxd4 6.Be3).
It's true these are just surface level engine evaluations. However, considering the book you're referencing on the Ryder came out in 2011, I highly doubt Stockfish is missing any crucial analysis that book has which would change its mind in any significant way.
Of course, if you're fairly low rated and believe you can trap a lot of the opponents you face, then the opening may be played as a surprise weapon. But objectively it could be considered losing.
