The debate of Presta or ShraderSchrader is mostly religious and often based on poorly misunderstood facts or historical differences.

Rim Width - inRim Width. In the 21st century, the problem is less about the strength of the rim and more to do with fitting the tire beads and valve into a narrow rim. If the rim is wide enough to accept a ShraderSchrader and mount the tire, its strong enough. As we are discussing MTB's - the last time I ran a rim too narrow for ShraderSchrader on a MTB was 1993. In the last decade, MTB rim widths are getting wider so it makes no difference what valve you run.

Edit: Weight :Weight. Presta aare marginally lighter,lighter; only you know why you care so much.

Length : AlthoughLength. Although long ShraderSchrader valves are available, if you have deep rims you are more likely to find Presta in long valves.

Pressure - ItsPressure. It's commonly stated that Presta is better at pressure - Schrader are used to contain pressures of over 600bar. They are used in MTB shocks (up to 250 PSI ) and you carsyour car's air conditioning unit (200PSI, expected no gas loss for a decade), so I think that myth is busted.

Inflation -Inflation. Presta had the edge way back before the days of plastic heads and computer engineering. In 2017, if your pump does not have a head that successfully inflates a ShraderSchrader every time, bybuy a pump worth more than $1.

Robustness -Robustness. From personal experience and anecdotalanecdotally from internet discussions -, Presta is prone to having the end broken off by some combination of one or more of clumsy novice and cheap pump. I have not done in the last couple of decades... Shrader Schrader really do require the caps to keep rubbish out of the core (although plenty don't and seem to last OK).

Reliability - ShraderReliability. Schrader are used in every car tire in the world. Presta are probably at least as reliable, nuf said.

Valve Length -Valve Length. Although tubes with long ShraderSchrader valves are now available, itsit's more common for rims requiring long valves to be Presta.

So why use one or other -? I mostly run Presta because many people still think Schader Schrader is a mark of a BSO, and although I ride a 10 year bike, I would not be seen dead on a BSO.

For tubeless though, I think the balance swings to Schrader - bigger hole for putting the slime into the tire. Bigger hole and for initial fast inflation to seat the bead.
