i only shoot color negatives.
this year i've pretty much only used superia 800, which hasn't too much grain, is cheap and allows me to shoot in any light condition with higher speeds: 1/1000 at f16 on the brighter side, 1/60 at f0.95 on the darker side (night streetlights).
bought some new portra 400 but only shot the 1st roll last week, picking it up today, tested shooting at 1600 and 800 with no push, let's see how it goes!
i also really like fujicolor 100, it has very fine grain and well saturated, the scans i get from it are amazing and it's dirty cheap for brazilian standards (R$5 a roll, roughly $3. a superia 400 will usually go for about R$15...)
