I would choose Patagonia out of those two, but here are some other brands to check out:

Paramo is very good quality and an ethical manufacturer. No lifetime guarantee, but they have a guarantee against defects and also a repair/alteration service.

Rab is also superb quality, check out their Latok or Resolution insulated jackets which would be in your price range on sale. They have the same sort guarantee and repair services as Paramo, and they also have a professional wash service - a lot of waterproof jackets are ruined by incorrect laundering. I have a lightweight Rab jacket (women's Kinetic) and I love it, super breathable but the rain just off it.
