>>6911184it's up to personal preference for the most part, but Brutaka is often cited as the best Titan set because of his solid build, great colour scheme, very well integrated hidden feature and generally awesome design
most Bionicle sets came out in waves of 6 different-coloured good / bad guys
my personal favourite good guys are the 2001 Toa Mata, favourite bad guys are the 2007 Barraki by far
