you posted in the Sherwood subforum which means we aren't supposed to give alternative manufacturers options.
The Wisdom 3 uses DSAT algorithm which is what the PADI tables were based on. It is a very old rather dated algorithm that is very liberal especially for repetitive dives with quick SITs.
You don't find many reviews because these types of computers are very expensive for the limited amount of options they give a diver. Review whether you really need AI and what you gain from it, the dive time remaining notifications are somewhat helpful, but shouldn't be part of your dive plan, if you're doing ocean dives you should know your SAC, you should know your planned depth, and you can calculate your approximate dive time based on these numbers, it's nice to track your current sac rate, but that's pretty useless in the grand scheme of things. Sherwood has user replaceable batteries, most Suunto's do not, so that is a perk.
Frankly I'd do one of two things, I'm in the Sherwood forum, but they don't actually make their computers and certainly aren't known for them, so I'll break the rules for a bit.
Consider a Shearwater Petrel, it's a vastly superior computer, it is made in Canada so you are supporting local business, and will also likely get it cheaper than any of the other computers since your currency exchange rate shat the bed recently.
Consider a wrist watch style computer if you are travelling, Sherwood Amphos, Oceanic Geo 2.0, Oceanic Atom 3.1 etc. Will be more functional with mixed gas if you move that route later, less likely to get broken on a dive boat if a tank gets pushed on it, and you can wear it instead of your normal watch while on trips.
The Amphos Air, or Atom 3.1 you are a bit more expensive and still get AI though wireless, but Oceanic recently redid their transmitters and they are much more reliable than they used to be, or save some money and get them without the transmitters and realize they don't actually do much of anything. Console computers are nice in theory, but they are big, heavy, clunky to use, and unless clipped off can cause some wicked damage to the environment, overall just not a great option. The computers above *no direct experience with Amphos, just listed it to be nice in the Sherwood forum*, are all much more versatile than a console computer, and easier to use with nice side push buttons
