Eshopps S-120 Mid vs Premier

[Sullivmw]

Just seeing if anyone has looked into the differences between the premier line and the Mid Level Line by Eshopps? I have read the descriptions online from the manufacture, but walked away not really seeing the real world difference.

I am looking to buy the S-120 for a 60g cube, and couldn't determine if there is a performance difference, a build quality difference, etc? There is about a $90 difference between the two - so I am sure some fellow reefers have done a deep dive into the cost vs performance ?????

S-120 has the EDDY bubble plate, twist off body, and the trim is transparent blue rather than opaque purple. That's about it. I purchased the S but there are a couple guys on the forum who have the X, there's a thread going on about it if you do a search.
