The TK21 is the more recent model and is slightly brigther.

The main difference is that the TK21 has a XM-L U2 Led while the TK15 has an XP-G R5.
I don't have any flashlight with an XM-L U2 but I'd assume is floodier than the XTP-G R5.

As for runtimes: according to Fenix the TK21 wins on Low but the TK15 is better on Mid and High. Not much of a difference on Turbo.
As for the throw, they are the same.

The TK21 is longer and has a wider head.

Check the UI description and see which one you like best.

It would probably make sense to go for the TK21 but since the differences are not so big, if I found the TK15 at lower price I would be happy with the less recent model.
