I just went through this process over the past couple of weeks. Tested the 10x42 SLC, 10x42 EL, 10x50 EL, and 12x50EL.
I thought the SLC were a pretty significant step down from the EL as for my enjoyment looking thru the binos. I truly didn’t think they were much of an upgrade over my Maven B2s, if one at all. That said, I know guys who prefer them over the EL.
For me, the EL absolutely took it to a whole new level. I was in between the 10x50 and 12x50 and in the end I went with 10x50 for a few reasons. The 12s concerned me a bit, wasn’t confident I’d be able to hold them steady and some questions to people who own them confirmed the concern. The 10x50s have a larger exit pupil than the 10x42s and I perceived them to be a fair bit brighter than the 42s. Whether that’s real or not, I can say that the 10x50s absolutely blew me away. The FOV is slightly larger, to boot, and a lot larger than the 12s.
Something else I found interesting, I was one of the unfortunate people who saw the “rolling ball” affect they ELs when I first viewed they them about 6-7yrs ago. It was terrible and I would have told you ELs were the worst binos for me. I no longer see that same thing, for some reason, and the view is absolutely better than any other glass I’ve looked thru.
But yeah, as stated above.. if you want 12s, the ELs are your only choice.
