Rain Jacket/Outer Jacket

[eec]

I know the idea is "wet and warm", since eventually you're going to get soaked, but I'm wondering about what level of outer jacket to purchase. Heavier, more durable vs lighter, more packable.

I'm looking at these options:
Marmot Optima GoreTex PacLite, around $140, lighter, more packable, durability?
Endura MT500, around $210, bombproof, but seems like it would be bulkier
Showers Pass Refuge, around $215, seems to be bombproof as well, but also bulkier(?), I've also heard bad reviews on build quality

So I guess I'm wondering if I should spend the dough on something that I know will keep me as dry (and warm) as possible, or not spend as much and rely more on under layers for warmth? I'm planning on having merino wool base layers either way.
And if I'm going to spend money on a jacket, I'd like it to be able to cross over into the non-cycling world, but I'm eyeing these specifically for TDR.

Any insight, suggestions would be greatly appreciated.

I've never done the GDMBR, but a fair number of 2-3 day bikepacking trips. I'll say what I bring for an outer layer totally depends on the weather I expect. In the New England summer, rain means finally I'll get cool. I have no concerns about getting cold while riding and wet, and only need to worry about dryness and warmth while sleeping. If I bring any top layer at all, I may just bring an ultra light wind breaker. In the fall, being wet can be an issue. Since it can drop below freezing at night, you need to manage your core temp a lot more. Relying on a down jacket for warmth, once you hit camp, you need a good rain jacket to keep your down dry.

On the bike I can be wet from the rain during a ride, as long as I can change after the ride.

I have 2 jackets that I use regularly. One is a Louis Garneau cycling windbreaker that works very well and packs down pretty small. I get soaked with sweat if I put too many layers on under it.
For rainy weather, I have a NorthFace Venture. It also packs down nicely, but again, I will get soaked under it.

I like to keep a dry base or fleece layer along for when I stop. Get out of the cold and wet and into something at least dry. It can be a challenge.

In mid 30's while riding with a base layer and jersey under the windbreaker, I'll get drenched

Lighter and more packable.

A light hard shell with a hood in a generous size with generous pit zips. Light is key when you use it as bug pro, and for the same reason a hard shell finish is useful. Something like Marmot Precip or Patagonia Super Cell works well, is reasonably light and is not terribly pricey. I'm sure there many products that would meet the criteria.
