The most common Trident AB complaint: bugs
Not impressed. Our first test had an issue and when we tried to make the changes necessary it just glitched and kept trying to load. So we created a new test, and it will not switch back and forth at all. Support tried to help, but doesn't seem to be able to figure out what is going on. We just want a refund and will try a different app instead.
The most common GemX complaint: support
Tracking is inaccurate even after 24 hours. The app doesn't collect data on orders or visitors at all. I wasted two days testing only to see results that make no sense and don't match reality. Support doesn't exist. The support app itself doesn't even work. No way to get help, no responses, nothing. Stay away from this app.

Serious problems reviewers reported
Billing disputes, broken stores, misused data and missing features. Each one is a single merchant's account.
The app is faulty and causes rework - it removed all our variant images and caused lose of sales. Now we have hours of rework to just get our website back to where it was before implementing this app.
I ran one test on one product detail page. the goal was to test the product images. Test didn't work as it should. I immediately stopped it. But the app destroyed our product detail page. All images were a mess. Can't recommend it.
when I hopped on a call they promised free trial for 2 years, haven't received it since months. Also there's almost no live chat support, making it difficult to communicate. App does not show ATC performance as well, must be bug.
