I recently went through a similar process after dealing with a couple medical issues that kept me from diving for a couple of years and me taking a couple more years after that to get the itch to dive again.
Most of my dives are in Puget Sound which doesn't always have the best visibility and as an older diver, my eyes aren't getting any better. I'm also a photographer and have prescription lenses in my dive mask, more to clearly see the viewfinder and fishes but they also help with reading the display.
I read a few threads comparing the Core series with Sheerwater and there is a pronounced bias toward Sheerwater, especially for more advanced divers. A dislike of the potential for the Eon to lockup if you miss your stop, no Buhlmann algorithm, and it can't display 2 gas contents simultaneously are the common reasons stated. The recall issue mentioned in this thread was the first I heard and while it doesn't impact the Eon series, overall service is a worthwhile consideration.
Here is a link to one thread.
Eon core versus sheerwater perdix AI
Since my main consideration is an easy to read display, I have no plan to become a technical diver, carry more than one tank or have a computer with Buhlmann support, I had been leaning toward the Eon. My research found enough felt it is slightly easier to read with the ability to select a simple display format suitable to recreation, NDL dives.
I happened to visit the Suunto website and notice the Eon Steel was on sale for 50% off and made an impulse order. The Steel was listed as "No Longer Available" the next time I checked, less than an hour later. I'm not sure if that means it has been discontinued.
The Suunto Eon Core with Transmitter and USB bundle listed on some online stores looks pretty tempting. I won't have a chance to test the Steel until late December or January but topside it looks good to my eyes. I assume I would have been happy with a Sheerwater and wouldn't discourage anyone from that option but the Scubaboard bias towards the Suunto didn't dissuade me.
