How are the Shimano Saint brakes? How do they compare to MT7 or Hope Tech 3?

Hello everyone, I'm thinking of getting the Fourplay PRO with SRAM brakes for 1699€. I have been doing trial on my cheap mountain bike for now, so this would be my first trial bike. Is it of good enough quality to be able to do some awesome MacAskill level tricks? What I worry about are the SRAM DB5 brakes, has anyone had any experience with these? I would probably upgrade them later on to something high end. Hope tech3 or Magura MT7, or are there any better? I could also get the bike with these installed for 1899€ but I would have to wait for another two months . How much would it cost me to get high end brakes (and pads and rotors if necessary?) later on? Thank you everyone!
