The below are my personal preference and opinion based on my experiences.
Paiste low-end set are not versatile - mainly for heavier types of Music - not Jazz definetely.
Bosphorus - does not have low or high end sets - they are good cymbals & are definetely Value For Money and make your money worth.....BUT
Bosphorus Cymbals in most of their BELL lack definition (the bell does not gives enough volume)....and though I say Bosphorus has many Range eg Traditionals, Gold, Antique, Turks, Masters to Signatures Type (etc) ....Most drummers prefer the TRADITIONAL - as it is more Versatile for use...so for Rock, Blues & Jazz - Yes you can use Traditional for Bosphorus.
To me - Paiste is my favourite Cymbals - I love those sound and if I want a Versatile Paiste Cymbals - I will only get the - Paiste NEW Signature - not the Signature Series....
Currently I'm using only Bosphorus & Paiste Signature & New Signature Series - plus Factory Metal Percussion.
Cheers !
