Yeah, I think it's important to note the distinction between Force connection and actualized ability. I do recall Vastor's extraordinary strength and physicality, but even Opress seems more advanced in his command of the Force.
Mace muses that Vastor's connection to the Force on Horuun Kaal rivals Yoda's, but Nick Rostu senses that Vader would hand Vastor his ass.

Not quite. At one point Mace did attack Vastor with a pair of lightsabres. Vastor blocked the attack with his shields and they talked briefly. Mace backed down when he realized anger was clouding his judgement.
That was all. They never had a full-on lightsabre vs. vibroshields fight. When they fought later it was bare-handed and in their final confrontation Mace won through trickery/strategy.
Anyway, I'd say Vastor would win in the jungles of Haruun Kal but Savage would win in a neutral location. That's not saying Vastor is weak or incapable outside of Haruun Kal. He isn't and would still be a formidable foe. But he does have a very deep connection to his home jungle that is a big advantage to him.
As I said I think Savage would win a fist-fight on neutral ground. Physically he's just as strong and tough, maybe more so, and he has a similar degree of natural ferocity. It would be a tough fight though.
