I used to be in love with St Feuillien, back when I could get a bottle for €1 at my local bar in France.
And the Bourgogne des Flandres, too. But I can barely remember the taste.
Had a Leffe Triple at Christmas, and it was indeed too strong and boozy, my vote goes to the radieuse (3L bottle by the fireplace at new years eve *sigh*)
