I go to the banana festival every year. I've had all of these varieties and many many more. I have three different varieties growing (including dwarf Cavendish). You can try gros michel at the fest, along with many more flavors.
I'll say first hand that gros michel is a much more flavorful banana than Cavendish. Its more fragrant and perfumed, and very sweet. But also, just about any other banana is better tasting that Cavendish. My Tahitian blues are delicious. And the star of our yard is our unnamed variety of apple banana.
The Tahitian blues are more mild and sweet. But with better texture than a Cavendish. But the apples. They're the dream banana. A but more tart and firm, even when iver ripe. And if you can let them get fully ripe on the tree, just amazing flavors.
The issue with the apple though is that the trees are massive and super aggressive. If I had more space I would just grow those, but it ends up being a few hours a month in management just to keep the apple bananas from taking over. There's a farm I'm helping to start and this is the variety we growing there.
Banana fest is only 15 for a wrist band and all you can eat bananas
