Resplendent (Golden) Chests? If they're along my way, sure. Normal chests? No, waste of time.
You're assuming that you're running TX for loot. Those people who don't open chests are running TX purely for the keys. Less clicking on chests = faster rift clear = more keys. In the end, it also means you clear more rifts, so you will slay more enemies and get more loot from them.

I would say to go with strength one for this build, since it should be better for your earthquakes, or that I have been told.
