Patka is more protective than general ballistic helmets, unless you are against mortar, artillary or fragments that can come at you from any direction, which the soldier in kashmir do not face.
What they face are terrorists armed with Aks and encounter that is most of the time happens in relatively close range.
With patka you are atleast protected from front, with normal ballistic helmets you aren't.
Normal ballistic helmets, are designed to stop pistol calibre from all directions where it covers the head at most.
Patka has a metal band at front designed to stop rifle rounds, from sides it's usual pistol calibre protection, from top no protection only padding( for weight saving)
You can also add a a modular ceramic add-on plate, to increase protection of standard ballistic helmets to rifle calibre from all directions, except top.
It's more protective than patka, but also heavier.
Now, new helmets have developed that can stop ak rounds from all direction.

And small scale orders have been given
Indian firm MKU Limited has delivered its Kavro Doma 360 ballistic helmet to the Indian Army, company officials confirmed to Janes at Aero India 2025.

But until it becomes standard, it's much better for soldiers to wear patka or helmets with ceramic add-on than conventional ballistic helmets.
Now in a "war situation", fragments( from artillary, mortar, bombs etc) are a big threat, so I would chose normal ballistic helmet over patka, but kashmir is counter insurgency.
