Is there any advantage of using Presta over Schader or vice versa?
Why the difference?
presta are easier to get pumps on, easier to deflate, and will fit in any rim.
Nope, they're just different means to achieving the same thing. Makes sense to have the same valves if you ride with the same people all the time, but other than that, don't worry about it.
Schrader is more heavy duty, intended for downhill etc, whereas the presta valve is aimed at xc.
(I Think ???)

Now there was me thinking it was intended for tractors [& cars]

Oooh - cutting Uplink 😉
Heavy duty valves for (low pressure) DH...?
It really, really doesn't matter. Honestly. 🙂
Schaders make you cycle faster
Schraeder is intended for higher volume, presta for higher pressure. Practically, it make no difference

Take a look at the valve on your shock/forks.....
There is only one reason for Presta on MTBs - Slightly easier to deflate
It's been done a million times on here and nobody can give a better reason than that! 😀
Presta seals better whilst inflating as the valve closes with each stroke, shrader relies on the valve in the pump (the head of the pump holds the valve on your innertube open) which is why the tyre deflates as soon as you open the lever on the pump.
Which is why pumps are useless for doing pressure readings on presta valves, the valve could take a couple of psi more than the tyre to open if its stiff or be well under the tyre pressure if the line between the pump/guage and the tyre is leaking back into the pump, as above, the valves in pumps are usualy big, so let lots of air through, but don't seal very well.
Just try putting 120psi in a roadie tube with a shrader valve to see what I mean!
Presta = gay
Schraeder = butch

Fox air shocks use Schrader valves and I put over 120psi in my boost valve no problem.
There is one advantage of shrader over presta and thats the crappy valve stem is very easy to snap off on a presta, its very hard to do on a schrader.

TBH - I use both types [I may even have one of each on one bike] - I can honestly say I've never snapped a valve stem
Scraeder make it easier to get the sealant in when you're running ghetto tubeless.
Presta locknuts can be impossible to undo with cold fingers.

You could put 250psi in them no problem, because thats what they are designed to do, move a small ammount of air slowly, the valve in the shock pump will be infinately better than the crap one in the track pump, can you inflate your shock from your track pump, I know some expensive ones go north of 200psi for track bikes, but they cost a lot and have really narrow barrels and probably similar internal to the shock pump?
Shrader are arguably more robust as you said, which is an issue on a £300 shock dealing with 400+psi at full compression. But on a £4 innertube dealing with 100psi its less of a problem.
