Yes. Monero is more popular than ZCash as it has been the first cryptocurrency to implement a solid privacy algorithm which obfuscates transactions. While XMR has first mover advantage, ZEC has brought to the crypto world a new innovative technology called Zero Knowledge Proofs, which is quite effective in hiding transactional data. As it improves over time, it could stay in par with Monero, as a solid privacy coin for the masses. However, at this point, it cannot compete with Monero simply because it's privacy features are optional, while Monero enforces privacy by default.

Despite that, ZCash could go somewhere once it enforces Shielded Transactions by default, and it shifts to the new ZK-STARKS algorithm which is trustless and more efficient. It shares many of the same economics as Bitcoin, such as the maximum supply of 21 million coins in existence, and block emission rate. As such, it could rise in value over time as it grows in demand and usage within the mainstream world. Being a deflationary cryptocurrency like Bitcoin, it has all the odds of becoming extremely valuable in the future. Just my opinion
