I've tested many, but Infuse was the only one that satisfied me. It plays absolutely everything on absolutely every Apple device. iCloud sync is perfectly implemented and truly unique in its perfection. It's like it's on one device. Dolby TrueHD and DTS are transcoded and passed on as lossless PCM. Dolby Vision is output correctly, and profiles not supported by Apple are converted to HDR perfectly, without any coloration or faded images. Big praise to the developers; this work really deserves a bit more money.
