I would like to choose BURST, not CHIA. My choice is not because technical aspect but I think CHIA is risky and BURST can take advantage of a hype on CHIA to recovery from its bottom.
I consider BURST as Ethereum Classic that had good growth by taking advantage of Ethereum upgrade.
BURST is a tried and tested blockchain network with years of experience. Chia, on the other hand, is relatively new to the crypto space (which brings a high level of risk to its holders). We could say that going all in Chia is like going through "uncharted waters". Somehow, Chia has obtained a higher price per coin than BURST itself. This could be related to aggressive marketing/promotion efforts by the Chia team. BURST folks better do the right thing for the project could go all the way down the drain. Something innovative that would "blow" the entire crypto/Blockchain space, could help attract investors into BURST.
Ultimately, what matters is mainstream adoption for a cryptocurrency project to survive. Adoption for BURST has been quite low, but it's still "kicking" after all these years. Both Chia and BURST have hard drive mining capabilities, which bring a high level of accessibility to people in the mainstream world. It's much easier to mine coins with a HDD than an ASIC or GPU. Time will tell us whenever the new consensus algorithm (Proof of Capacity) will become a success or a failed experiment. Just my thoughts
