If no boost is allowed, I would test out which is better. Personally, I run Tekin, and they're latest version is awesome. I just like the "full" capability of wide adjustment capability. That's just my opinion. Although, I've always wondered about the "amperage" thing (120a), because Tekin doesn't advertise it (I could be wrong). There are others out there that puts out the same or even better, but is it worth it to run in "stock" class? I don't know... At my local track, nobody runs that brand...not even for 1/12th class. But, for 1/10 stock TC, WGT, and 1/12....the majority of us run either Tekin or LRP.
