High Sierra hiking, can't decide on a darn rain jacket

So i've used the search function and done a lot of reading lately. I'm about ready to sell my near OR Helium 2 due to sizing as I am on the fence between a M/L and don't like the fit of the L i got.

So it seems most agree that ventilation in the form of pit zips and mesh pocket is superior to any WPB in sustained rainy hiking. But the jacket I purchase will be used in the Sierras about 95% of the time as that is near where I live. I also have an Arcteryx Beta AR that i would use if prolonged rain is in the forecast which weighs about 16oz and doubles as my ski jacket.

Taking region into consideration and the fact that afternoon thunderstorms are typically short-lived, should i forgo pit zips and opt for the lightest jacket possible? I'm currently looking at:

marmot essence - dwr seems superior but warranty no bueno
montbell versalite
zpacks challenger - price tag on this is nuts though

I know I'm, overthinking this. The only thing i am certain on is the need to replace my Helium 2 because of sizing.
