If this is a renegade faction, I don't know what tech they would have but the schism between warriors and scientists would, I'd think, actually leave them behind. Potentially very old Chozo tech which was, ages ago, what ruled their Empire but Samus' suit (in general and) by/post Fusion is well beyond that of anything old Chozo. She's got tech from the Science Lords of Bryyo to Luminoth tech to ancient Chozo tech to modern Chozo tech to an evolved (SA-X + Metroid) power suit by the end of Fusion.
But I'd sooner be more concerned about Samus vs. an older breed of Chozo warrior. Samus is from the same pool of bioengineering as the Metroid's (ie. pinnacle of Chozo technology as we know of it). She's a cross-species supersoldier with the DNA of an effectively legendary Chozo warrior, raised by the Chozo and MB, and sporting a body count of multiple planets, a space station, the entirety of the space pirate race/society/everything. Who knows what Phazon did to her body but she was also able to withstand that *stuff* even as she delved into multiple leviathan seeds and got drenched in it repeatedly.
Doesn't generally seem fair to compare her to any single warrior, hah. She's more of a natural disaster.
