For me, walang best brand talaga. At the end of the day, nasa gumagamit yan i.e. kung hinde maalaga at maingat, kahit anong name brand eh maaring masira pa din.
However, as far as support goes....umm...walang lamang na brand para sa 'kin. Been a notebook user for years and nakagamit na ako almost all of the name brands (except for Apple) and in one form/way or another, sumakit din ulo ko/namin dito sa office sa support/quality of service at one time. Pero as far as our collective experience here at the office goes, we had less problems in terms of support and turn-around time with Toshiba.
