Aluminium or titanium screws?

[Zuippe]

I have seen a couple of build videos where steel screws are replaced with titanium ones.

At least where I live aluminium screws are cheaper and easier to find than titanium.

What are your thoughts on using aluminium screws in Stealthburner and gantry?

If you're chasing grams, it's an option. Otherwise the weight savings are minimal compared to the weight of the motor, hot end, fans, and extruder gears, much less the overall toolhead.

If you remove the extruder and replace it with a Bowden setup you'll save way more weight than switching from steel to aluminum screws.
