I don't know what it is with me liking nominally mediocre French Heavies (I think the M4 54 is extremely competitive) but I've been finding this tank really excellent.
For all you lose in mobility (and it's still fair in this regard, 37 kph, which it reaches on flat, is the same as the T110E5), you get an excellent gun. Holy balls this thing lays down mad damage. The gun handling, intra clip reload, aim time and 5 shots on a reasonable reload time just make this gun THE BEST tier 8 heavy tank gun, maybe on par with the Caernarvon. People compare this gun to a Lorraine gun but there's not even remotely any comparison. If you hit 2.5 damaging shots on average in the Lorraine, you hit 4 damaging shots on this tank per mag.
The turret is small and the hull armour is pretty good at bouncing shots when you use that smexy -10.
This thing has 90mm side! Side scraping is pretty doable in this.
What I don't get is how this tank is actually pretty mobile. The traverse is good but it has 12.5 horsepower per ton and not very good soft stats and still can easily reach and maintain 37 kph.
