I have both TIdal and Quboz. They do not have the same albums so having both is worthwhile.
I did quite a bit of listening to MQA and don’t find it’s worthwhile, overall, but I like Tidal’s record collection. On my DAC there’s no way to use it with my preferred filter so I leave it off, but Roon does some of this.
As has been written elsewhere, while MQA may claim to be high resolution, it’s also lossy. See the Benchmark Media paper on it. In a world where 100mBit+ speeds is normal for audiophiles it makes MQA compression less important.
I'm also lucky enough to use Roon which will do 96/24 bit MQA decompression in software so I don't really think much about the whole process.
