Not sure you can generalize - I use two solid state phono stages and one tube based one and all sound quite good. The best is a solid state classic - the John Curl Vendetta which is the best I have heard although we ran it against a last model Herron VTPH - 2A with which it was neck and neck.
My tube stage is a CJ Premier 15 and although an older model it also is a good sounding phono stage.
