On both games it depends on my character class. However in ME2 it depends also on a mission.
ME1:
Soldier: Liara and Tali
Engineer: Liara and Ashley OR Liara and Wrex
Vanguard: Garrus and Kaidan OR Tali and Ashley OR Tali and Wrex
In general: to keep biotic/combat/tech abilities balanced. Unlike ME2, all of them were useful in almost all missions.
ME2:
Sentinel, figthing organics: Samara and Jacob. Both with pull field and Shepard with unstable warp. In addition squad incendiary ammo from Jacob.
Sentinel, fighting synthetics: Zaeed and Tali/Legion. Zaeed provides disruption ammo and tech expert - crowd control.
Any character, fighting unknown enemy: Miranda (the only character except sentinel Shepard that has both warp and overload) and squadmate with powers that Shepard don't have (i.e. biotic for if Shepard is engineer/infiltrator, etc).
In general: selecting characters profiled both for Shepard and mission.
I know that's not the question of that topic, but that is my answer: personal preferences doesn't play any role here (although I love Tali's "With you Shepord!").
