Done both. Centri blower easy install and cheap, relatively. Easy tuning. Good power, very consistent, reliable, low-stress fun.
Custom twin turbos, difficult install, challenging tuning, broiling underhood temperatures, wickedly unsubtle sound and power, a grenade waiting to go off.
Given the choice, I'd go with a positive displacement blower, screw type, as they don't bull**** around with compressing air in the volute, the way turbos and centri blowers do. They provide gobs of air at atmo and, as such, aren't constricted by needing tons of rpm to produce boost, have good flexibility with pulley changes, and don't turn the head unit into a big heat sink.
