I've only ever seen Tsai Ming-Liang's Vive L'Amour & The Hole, but I hated them both... as for Hou Hsiao-Hsien, I can't say exactly what I love about him, but I've seen everything he's done since 89's City of Sadness, and I absolutly adore each one... but for my money, Edward Yang is still the best Taiwanese director.
