Even though it has 3.7 stars for berries, which is below a stego, a stego is a much better berry farmer. Stegos can get up to 75 berries per a bush (2x), while bears can only get 50-60 (2x). Still a good berry gatherer but a better Rex substitute than a berry farmer.
Faster than a giga, strong as a rex, with some levels can get to 1k carry, can gather and eat both berries and meat,can even gather fiber, if you tame a high level one you have a super gathering and combat mount. Unmatched in utility.
