The EL has no fluorite (triple) objective lens. It has no field flatterer lens. Therefor it has no RB effect. It has a better balance. The FOV is a little bit smaller and the tubes of the SV are slimmer so it is more lightweight.
The SV has also a higher lighttransmission.
The EL is a hell of a bin IMO and the SV is the upgraded version with a lot of pro's and some cons.
