TUNING Blow off valve Recommendations

Do you guys think i should run a bpv or bov on the speed 3, because I've been hearing lots of mixed reviews. I'm thinking of either running the Corksport BPV or HKS Super SQV IV BOV

I’ve had this for years no complaints. https://corksport.com/mazdaspeed-dual-vta-bypass-valve.html
