When you get to the SLC series, the jump between grades gets way smaller. I have looked at the same deer in South Texas through my SLC's and the rancher's EL's, and he got maybe a minute more visibility in the treeline than I had. If I had not already known where the deer was, I might not have been able to find him.
He did have an older pair of Zeiss 15 x 56mm that were unreal, but not very handy. Weighed more than double my Swarovski's.
Swarovskis are mainly for bird watching. I think the differences in cost between SLCs and ELs are all for reasons deer hunters don’t about about. I think the SLCs are actually as good/better than the ELs for deer in low light.
