"but there is not much between them both then"
The cheaper reels are a good value, and will do the job. They feel more fragile, and I find engaging the spring clip difficult, so usually bypass it.
The Hewes reels are much better made, and are a bargain at the price, considering the craftsmanship and precision and sturdiness involved. The spring clip is well designed and easy to use.From a users perspective, either will do. I find the Hewes easier to load properly, and they should last indefinitely.
