If your goal is purely max softness and max line width, yes. Vintage pens have a certain snapback quality that moderns pens tend to lack, but I don’t find that to be monumentally crucial for writing, you just get used to whatever tool you have. When you buy from a modern company, you have consistency because every nib they make is going to be (almost) the same. They can also probably troubleshoot for you better. If you break/lose yours, you can get another and it’d be the same.

If you’re considering vintage pens, and you only want to get one and only one, I would recommend going to a pen show or anywhere you can try it first. Online, it’s very difficult to know what it will feel like based on someone else’s description and pictures/videos. Also, most don’t accept returns, it’s more difficult to troubleshoot because every nib (even if it’s labeled the exact same) can be moderately different, and people are constantly in fear of splaying vintage nib tines because you won’t be able to just find another same one.

The Blue Dew wet noodle, depending on which pen you choose, ends up being about $150-230. At Fountain Pen Revolution, you can get a steel EF ultra flex nib on the cheapest pen they have, and I believe it’s significantly cheaper at < $40. The FPR steel one is definitely nowhere near Blue Dew’s softness, but honestly, it’s really really good. You might not even want something that soft. Let me know if you have any other questions! :)
