To be clear there is nothing "more" taxable about taler than crypto, it's just integrated with the traditional banking system by design while crypto is self-reported. Also since taler is a payment processor and not a currency, that tax is presumably sales tax rather than capital gains tax. I don't know if this qualifies as "better" than crypto for payments, I'd say really depends on what your use case is, but I appreciate that taler tackles the problem of paypal by simply doing open source paypal, rather than invent a whole self-sovereign currency.
