It all depends, personally I think the t55 is the better option for an all rounded easy to use strong tank. While the 2s38 I kinda suck with and also you get no missiles and a 57mm cannon. If you want to keep grinding ussr after 9.3 get the 2s38. If not get the t55 or just get talismans on other 8.3-9.3 vehicles
2s38 is far better and more versatile, but you also play at a br that is oversatured with bs teams and ridiculous cas and helis. So overall for enjoyment and getting good matches that gives more research I'd say the flamer tank tbh. 9.0-9.7 might as well be 10.0 as it just faces constant up tiers to 10.0 anyways. Doesn't matter which nation I play, if it is within 1 point of 10.0 it is near guaranteed an uptier. Go for the flamer tank, your sanity will thank you for it.
