I’ve had 2 or 3 fixed 10x, the 3-15x, and the 5-20x from SWFA. Out of all of them, the 5-20 was way ahead of the rest, and is what I would pick if I got another without a doubt. Even with the weird reticle. If the 5-20 was out of the equation, I would take the 3-15. Really the same optical quality as the fixed imo, as well as same feel, but has options for the different magnifications to choose as needed(obviously). With that being said, I never had an issue with any of them. Something else to throw in there - I’d say it’s definitely worth the extra money to get the side focus on a fixed, but that’s also getting you that much closer to 3-15x price range. Hope this helps
