Me too, am even a bit shocked to see this list. 
Happily, there are some differences, caused no doubt by different listening experiences; namely:
1. I love Respighi, especially his later pieces, but found the Vetrate a bit bombastic at first hearing (comparable to other war horses like the Pini and Feste Romane) and never played much attention to it since then; my Respighi favourites are the Fontane, Trittico botticelliano, Lauda per la nativitá del Signore, Metamorphoseon Modi XII, Belfagor Overture, Concerto gregoriano, La Primavera, Ciaccona, Antiche danze ed arie per liuto III, Maria egiziaca. Tell me: what am I missing (nodding at Jeffrey too: yes, it must be completely my fault).
2. The same with Tubin: find his symphonies one of the finest cycles that I know and love them dearly; but almost all more so than the trepid Fifth (that I even heard live, in Utrecht, just as I heard the Sixth and (unfinished) Eleventh in the Amsterdam Concertgebouw. Why not 4, 6, or 8? 
3. For me, Miaskovsky is No. 6 and No. 27. Please tell me more about No. 17.
4. Franck, really? 
I was a little bit moved when I wrote that (I had a overdose of shocking music)

About Tubin, any of the 1-7 are splendid, all of them I like so MUCH!!!
The Miaskovsky's 17th has a magical slow movement, one of his finest ones.
Franck... Le Chasseur Maudit is great (maybe not bombastic), his most succesful attempt in the tone poem.
I share your views on nearly all those works and am encouraged to listen to the Novak again. For my brother the Walton is about despair turning to defiance and I like that analysis. It remains one of the greatest British symphonies along IMHO opinion with the two (or three) by Elgar, Vaughan Williams's 4-6,Bax Nos.3 and 5,Arnold No.5, Moeran's Symphony, Rubbra's No.4 and 1 and 8 by Havergal Brian.
Haitink's recording is an epic performance of an epic symphony.
That recording is slower comparing with others. I find it more solemn, the climaxes are overwhelming, there is slightly more time to enjoy. In some works I prefer slower performances to catch some details in a better way. Fortunately, this symphony has had many excellent recordings.
Some time ago I did not listen to it and I was pleasantly shocked. It can't fail!!!
