The way I land my tail-dragger is by touching one of the main wheels down first, which will force the other main wheel down a split second later then depending on the speed apply some down elevator. It's rare to have my plane bounce back into the air when landing this way. It is a very graceful landing and you can stick it to the ground pretty much every time.

As a rule your main landing gear are stronger than the tail-wheel and can absorb more impact. For this reason I think putting your main gear on the ground first is more prudent.
