My B&M and Intamin count is almost equal (currently B&M 4- 3 Intamin) but Intamin is my preferred choice. Out of the 4 B&M's only 2 really made an impact on me, Nemesis and Inferno being huge let downs, while surprisingy i found Air and Oblivion wonderful rides. Batting for Intamin was Shockwave, Colossus and Rita: QOS and after each one I had a smile beaming from ear to ear. Yes they had a rougher edge but they were a lot more enjoyable. Intamin for me.
