havent had experience with the ones you mentioned, but i had our suzuki esteem serviced at pilhino along edsa with no problems. madami din ibang suzuki doon.
Ako sa Pilhino at EDSA rin nagpapagawa ng Esteem. But that was several years ago. Eventually, I realized that it is expensive that have my car serviced there especially after the warranty expired so sa Shell na ako nagpapaayos.
As for Pilhino, medyo OK naman sila. Not as professional as the Toyota Service Stations pero tolerable na.
You can't watch while they fix your car but this is the practice for all CASAs.
If I were to rate them, mediocre lang sila but OK pa rin.
