I just played through Portal again, using a DualShock 4… up until Test Chamber 18. It was simply not possible to look left/right without ever-so-slightly moving, enough to miss falling back into the portal. Mouse and keyboard- cleared it instantly.
Edit: I may try again, using a controller that has 8-way detents on the analog sticks (i.e. GameCube gamepad)

Personally on the steamdeck gyro, once I got used to it, has become indispensable for a lot of games to solve this sort of problem
