I voted for DeepOnion. It's looks really promising and they are giving free airdrops everyweek. The price is good now but I hope it will increase in the coming days. Im just hoping deeponion will be more popular and will be listed in large exchanges.
Comparison with other coins
In this section we will answer the common question of "How does
Spectre compare to X?", where X is one of the following coins.
CloakCoinBoth Cloak and Spectre use PoS only and don't have masternodes.
Cloak has 6% inflation, Spectre has 5% inflation.
Both have a block time of 60 seconds.
Cloak uses the proprietary terms "CloakShield" and "ENIGMA transactions", while Spectre uses Tor and ring signatures. This makes Spectre technology easier to understand.
Cloak seems to also target applications sending data between each other via the Cloak network, while Spectre focuses on being simply a currency.
While CloakCoin has its own onion routing network, Spectre is part of the official Tor network. This makes Spectre more anonymous (as there are much more nodes participating in the network), and more difficult to censor.
Cloak's ENIGMA protocol seems to be based on mixing, whereas Spectre uses untraceable ring signatures that we find to be more efficient and also more secure: Ring signatures (using private fixed-size tokens) are information-theoretically anonymous, while mixed transactions could possibly be prone to correlation attacks and malicious nodes.
All funds are visible on the blockchain, whereas in Spectre, funds that are stored as private balance (tokens for ring signatures) are not publicly visible.
DeepOnionDeepOnion gives you free money, Spectre does not.
Both operate on the Tor network.
DeepOnion uses both Proof-of-Work and Proof-of-Stake, Spectre uses Proof-of-Stake only.
DeepOnion does not offer transaction privacy, all transactions are publicly visible. In addition, Spectre also supports stealth addresses and ring signatures for private sending and receiving of coins.
Users are able to send encrypted messages using DeepOnion, this does not quite work with Spectre yet, although we will be adding that feature.
DeepOnion is a marketing-airdrop scheme on Bitcointalk, whereas Spectre had a plain ICO.
The DeepOnion dev holds more than 50% 
of the coins at this point, whereas the Spectre devs only hold about 1-2% together. Therefore, DeepOnion must be seen as being completely centralized at this point, which makes it zero value, whereas Spectre is completely decentralized.The DeepOnion dev is rich because he owns >50% of the coin supply of DeepOnion, whereas the Spectre devs are funded by the community.
The Spectre project has a vision that goes beyond private transactions and targets to establish a private payment ecosystem similar to cash, whereas DeepOnion does not seem to have any further goals beyond having an anonymous currency.
MoneroMonero is a much bigger project than Spectre and has a lot more devs, but also a much higher price. So Spectre has bigger potential to grow.
Monero uses Proof-of-Work, Spectre uses Proof-of-Stake.
The Monero wallet is mature and stable, while there are still some bugs in Spectre.
In Monero, you can send money anonymously, while this does not quite work with Spectre yet, because there are too few "tokens" available for making a ring-signature. We want to make Spectre Tokens (for ring signatures) the default in future versions, which should solve this problem.
Spectre has a rich list, while Monero does not. This comes from the fact that Spectrecoin's anonymity is an add-on to normal Bitcoin-like operation at this point, so anonymity (and storing coins as tokens instead of on a public address) is optional in Spectre. We want to make it the default in future versions. Spectre coins that are stored as "private balance" in the wallet are not visible in the block explorer.
Spectre has native Tor integration and all nodes run as hidden services. Monero plans to add an I2P implementation called "Kovri", but it's not the default for Monero yet. Monero can also run via Tor, but only using it as a proxy that uses Tor exit nodes, which comes with some problems (see the Tor integration section).
The goals and vision of Spectre and Monero are different.
In a Twitter post [1], "fluffpony" (the Monero project leader) noted that using Tor hidden services in Spectre might be susceptible to isolation attacks because .onion address are costless to create. This problem is mitigated in Spectre because the onion addresses used to join the Spectre network have certain requirements, which requires the user to "mine" for a suitable Tor public key first before joining the network. Also, like most Bitcoin-based wallets, Spectre has sophisticated security mechanisms for node selection, so running an isolation attack is not so simple.
Read a while in the forum and you see whichh effort is in this project
