I think that is highly dependent on where you are and what your greatest concern is.

If you were going to be flying in the Minden/Reno/Truckee areas or a similar congested airspace, then without a doubt I'd say buy the transponder as the airline traffic needs to see you on TCAS and ATC needs to know you're there.

If you're in a more remote location without much GA or Commercial Aviation and you're more concerned about glider/glider interaction, then Flarm is the clear winner.

Both is clearly optimal.

yes

Another Flarm question for US pilots:

If you can afford either a Power Flarm or a Transponder, which one
would you purchase?

Thanks,
