Alright, lemme break it down.

Strength/Durability; Teridax: Thanks to the GSR, his power caps at Star level since he can destroy suns. With the Emeralds, Mephiles would only gain enough strength to match the GSR if you use some high-end calcs on VSBW. Otherwise, he'd only become stronger than base, which hardly justfies a jump in power to Star level. So I'd say Teridax has the strength advantage.

Speed; Teridax: The GSR can cross planetary distances in a short time, so he'd be over 100X faster than light. Mephiles would be under 9X the speed of light since he kept up with Sonic before he became that fast. I think that one's pretty clear-cut.

Intelligence; Teridax: Not to undersell Mephiles or anything, but he recquired time travel & trickery to get what he wanted. Teridax made all his planning all on his own & rather than outright tricking people, he simply played them into his hands. I give intelligence to Teridax.

Experience; Teridax: Teridax is over 100,000 years old, & has accomplished a TON. Mephiles is (presumably) over 210 years old, but we hardly know what he's done in that time. So Teridax wins this category via quality & quantity.

Arsenal; Probably Teridax: With abilities like Mind Manipulation, Fear Manipulation, Illusion Creation, Corruption, Possession, & several other things, Mephiles will have a serious run for his money.

Except for one thing.

Time Travel; Mephiles: Since the GSR has no control over time, Mephiles could easily go to a time when Teridax didn't have the GSR, & kill him in this much weaker form. While the GSR might kill him before he can time travel, Mephiles has regenerated from a gaseous state, so it'd take a good bit to kill him before he decides to time travel. With Teridax in his base form, Mephiles takes strength, durability, & speed while Teridax keeps the others. Teridax's arsenal will still give him trouble, but I don't know if it'll be enough to beat Mephiles with the Chaos Emeralds, or even base form Mephiles for that matter.

So my final verdict is just barely Mephiles in a somewhat close fight.
