Haven't dived the Suunto myself so cannot speak to anything besides their reputation, which is so-so. If you are buying your first piece of gear after fins and mask, I think your money would be better spent on a non-AI computer (Shearwater Peregrine for $450 or Deep6 Excursion for $200 are both very solid), and start working on your other gear, like suit/regs/BC.
But if your mind is made up on a wrist-mount AI computer, the Shearwater Perdix and Teric are world-class. I love my Teric . As for your eyes, different people with eye issues prefer one over the other, probably holding one in your hand and looking at the screen would be helpful.
I have approx 1000 dives since 2015 on my Eon as well as 300 or so on my Perdix (since 2018) so feel fairly informed on both
The" So So reputation" of Suunto is basically a SB thing with lots of ill informed nonsense written and hearsay repeated. Even the pressure sensor issue was something blown out of proportion (lawyers making money) in the US. Components fail, and an incorrect depth reading either on a dive computer or an SPG is pretty obvious it the diver is paying attention.
The Teric solved one on my main bug bears with the perdix (2 button menu) but since its a small watch computer it's not comparable.
Suunto pricing in the US was (is) daft probably down to Huish. The differential between the Eon and the Perdix made it a no brainer to go to Perdix. Technically speaking there's no difference between the two from a NDL/Deco time standpoint. I dive them side by side, they give similar dive and deco times (by similar within 90 seconds of each other) on comparable settings - even after a sequence of 48 repetitive dives some of which had deco.
My personal [subjective] opinion is that the graphical display layout is miles ahead of numerical displays - the Perdix screen suffers from poor viewing angle and lots of reflections in shallow bright water compared with the Eon
Other differences between the two really come down to personal preferences. I've said before, and continue to stand by the statement, that if I were forced to choose between the two I would choose the Eon since it has less idiosyncrises that annoy me
