If we refer to technique as the ability to physically manipulate the piano, then Hamelin, though not by much. Gould was an astounding technician but Hamelin exceeds his abilities in 19th century virtuoso repertoire, which Gould never really explored, with a few exceptions (Wagner transcriptions, Ravel's La Valse). They are similar in that they both have a "laser clean" quality to their playing, as Michelangeli and Hofmann did. That said, I think Gould is the greater musician, Hamelin still has to grow into the music, he often sounds flippant or superficial in some pieces; his Medtner playing OTOH is extraordinary on all levels.
