If I had to place them in order of preference (best first) I would choose 9, 5, 3, 6, 7, 8, 1, 4, 2. It so happens that I believe that this order roughly corresponds with results normally emerging from both music board polls and other evidence of popularity such as the number of different recordings available.
Beethoven symphonies are highly accessible works with very clearly memorable themes, and one hardly needs to be musically competent to see that they were the product of a genius mind. On the whole, I would guess that most classical music fans like Beethoven, and probably like his symphonies best of all. On the other hand I can understand why some classical music fans are not keen on this kind of material. It may be that they grew up with Beethoven symphonies ringing in their ears, but now suffer from over-exposure and are now either fed up with them, or regard them as good for an occasional listen only. Other classical music fans may never have liked them in the first place, either preferring perhaps the late symphonies of Mozart or Haydn or material of a completely different type and era. There may indeed be still another group who have not yet got round to listening to any or all of them, and are still exploring.
I am rather in the camp of still greatly liking Beethoven symphonies but liking equally, if not more so, the works of other composers, in particular Schubert who I regard as the greatest composer ever. I would rate his 'Unfinished Symphony' as the best of all symphonies.
Except for his piano works and late string quartets I am not a Beethoven enthusiast, but concerning his symphonies the ones I dislike least are No. 4 and No. 8.
