TF X9 vs. Convoy C8, or TF X8?

All things being fair, is the TF X9 worth $15 more than a 2800mA Convoy C8? I’m studying the reviews and it seems that they’re kind of an even match in output. The X9 has more heat sinking but with only one cell it won’t be on high long enough to need it, at least not on the batteries it comes with. (though I’m also buying a pair of Panasonic 3400’s)

Or would the X8 perhaps be a better choice? Similar [theoretical] output, option of two cells, and would pre-dose my (to be built) stable of lights with some variety.

Thanks for the time. :slight_smile:
