>>50059353>Unovan has better defensesYes by 5 fucking points in each stats and they're still below average and not supported by an adequate movepool. So it's only marginally better than Hisuian Samurott as a so called "tank" and still ill-suited for the role compared to any actual tanks (like Swampert). The increased speed and Dark type STAB help so, so much more, considering both forms are ultimately wallbreakers and cleaners (although Samurott is probably the worst known Water/Dark type).
By contrast Typhlosion's increased speed COULD theoretically help it a lot more for its intended role (there is a lot of stuff sitting between 95 and 100 speed) but of course it is also completely offset by Hisuian Typhlosion's Ghost type and unholy combination of Scald and Hex (and Typhlosion does look like a competent Fire/Ghost type if it retains certain moves such as Focus Blast).
