PETG and ABS have similar stiffness. Both are fine at the temperatures involved here.

PETG is easier to print and deal with. ABS puts out some bad fumes that require actively exhausting the printer outside if you're trying to print in the house.

ABS is harder to print. Getting good layer adhesion is hard. It's more prone to warping. You want a heated chamber, ideally.

PETG is a fine choice for this. Going to ABS wouldn't change anything.

Also FYI, most people prefer ASA over ABS for printing because it's a similar material with better properties almost across the board.
