My favorite type would have to be Horizontals for the same reason as above: larger area to hit, more stable, bigger disc, etc.
Im not a great fan of drums but ed wallaces DB5 (or 6 or whatever it is now) has got to be the best drum ive seen (if he can just stop his astro getting smashed lol).
Of course the ultimate spinners are the FBS as you have all the benefits of the horizontals plus you always hit and have great armour.
