@Tbeeeeeee great question!
In my experience Gore-tex has been a very reliable option in terms of durability over time for rain jackets. However, there are many brands that carry high quality waterproof breathable jackets (both Gore-tex and not) in a variety of price points that will last you many years. The question I have for you is what is your main use for the jacket? Are you hiking or backpacking with a pack on? Are you using it in cold weather or snow? Bushwhacking? There are a lot of variables that can go into a jacket's durability.
Additionally, one of the most important pieces of maintaining a jacket's performance over many years is the care you take in between adventures. A quality non-detergent based cleaner and dwr treatment every so often (depending on use) will keep your jacket performing well for you for years to come!
I’m a camp director, so I spend a lot of time outside for work, no matter what the weather is. I also hike and backpack, so my coat gets put through the ringer.
In all seriousness, it's hard to get a jacket that could be a "BIFL" (love learning a new acronym!).
The durability and waterproofness of a jacket depend on lots of things - what it's made of, what you use it for, how you care for it, how you store it, etc.
I would recommend this Expert Advice article (https://www.rei.com/learn/expert-advice/rainwear.html), which may help you narrow down the type of technology you want, based on how you want to use the jacket - you'll need to think about breathability as well as waterproofing.
Living in Seattle myself, I think a lightweight shell like the Marmot Precip or REI Co-op Rainier jacket is great for throwing in my pack because they are lightweight and packable. If I'm headed to the mountains on a wet day, an Arc'teryx Beta or REI Stormbolt are great waterproof/breathable options.
Fit will vary between brands, so it's always a great idea to try on a few options to see what fits your body best!
