What are the best conga in the world??
I like  LP...

who is the best woman in the world? what is the best car in the world?  I think this question is impossible to answer.

seriously, I think it is a matter of personal preference and the kind of music you like to play and sounds you want.   I'm very happy with my LPs but if money were no object, I'd by 3 more sets from different companies because each is best for certain sounds.   I really like Meinls but I've heard and played a lot of different brands (and hand-made with no real brand name) that sound really great in certain circumstances.
