Parry for me. 3, 4 and 5 grip me from first bar to last. The Fourth is probably the finest, but I love the breezy quality of 3 too. With Stanford, there are many beauties but my attention is usually not maintained so strongly. I love the Boult version of Parry 5 which was his very last recording at the end of a marvellous career. May be rose tinted specs from when I bought it on HMV LP in Queens Road, Bristol in 1980 but I think it stands up very well (I think Boult was around 90 at the time.) I remember thinking the playing was a bit ragged then, but strangely I don't notice that so much now. The Symphonic Variations are rather splendid too.....
