I "downgraded" from Swarovski a few times.
Short story:
Once simply due to cost vs optics. Twice due to glare or stray light control issues.
Long story:
First was 10-15 years ago with the latest and greatest 8x30 SLC. The overall image didn't agree with my eyes, but I also saw a lot of reflections and glare. Internal, and external off of the ocular.
Most recently with the 42mm SLC HD. Like CA, once I see glare it drives me nuts especially for the money invested. Otherwise, I really liked the latest SLC.
I tried the EL and NL but they seemed worse for me. In side by side comparison, the SFL handled stray light really well but not perfect. I have a big 50mm binoc that I have to work really hard to get any glare, but I want the same from a 30-42mm. I'm still looking!
That doesn't detract from the positive qualities of the SLC, EL, and NL. They are all really nice. However if we are being honest, they are not perfect. For birders looking up into trees, it's not hard to imagine a backlit tree causing glare. For hunters, peering into a shady hillside with rising sun behind it can be futile with some optics. I experienced this every morning on a hunt, looking on the dark side of a huge mountain. The rising sun would wash out the image, and there was no shade unless I made it myself or hiked a long distance into the shadow of the mountain.
I have gotten to the point where resolution and FOV are still very important but if I can't see due to veiling glare or whiteout, then it makes no difference! I was obsessed with resolution first, and FOV second, but have come to realize that there is more to it than that.
I really enjoy the beautiful image from Swarovski more than any other brand by a mile, but it's like a fishing lure that catches fishermen to me. I need a more well rounded optic, for my needs. I suspect that many people don't notice the glare, or simply accept it in exchange for all the positive attributes.
ETA - You can mitigate some of the glare by eye positioning but that doesn't always work with quick glances, especially in a hurry with one hand trying to get a fleeting glance. Or by shading the ocular, but that is not always easy. I tried a 7x28 last week for the first time and there was no way that I could avoid the glare, and I was mostly shaded. Very frustrating!
