Having met Ryno (sdcdev) and had lunch with him, I can honestly say that he struck me as being a decent guy. 10/10 would have lunch with again.
I guess my three concerns with ShadowCash, in order of importance, are:
1. Proof-of-Stake is cryptographically unsound, in the long run. I know this is a hotly contested topic, and I don't want to flog a proverbial dead horse. Nonetheless, I have seen no cryptographic proofs (or assumptions under cryptographic models) to convince me that Proof-of-Stake is secure.
2. Being forked from Bitcoin is a blessing and a curse. Merging bug and security fixes from upstream Bitcoin (which will remain the target of more powerful proving and attack than any altcoin for the foreseeable future) is great, but it is going to be progressively more difficult to do so. The risk is exceedingly great that (as has just happened over the last few days) Bitcoin will reveal a security hole, and a cryptocurrency forked from it will not have implemented the fix.
3. Bitcoin's use of secp256k1 is...ok, but given that SafeCurves (Daniel J. Bernstein and Tanja Lange) view secp256k1 as unsafe, the use of the same curve is a little bit of a risk (Monero uses Curve25519).

Where do I begin?
lets see...SDC has been increasing in price constantly overtime while XMR is declining since it was first launched.
That is false, both have fluctuated up and down. SDC traded early at a peak 38K sat, traded several months later at 15K, had a recent high of about 80K, and is now about about 55K.
Likewise XMR traded early at a peak of 1m sats, for a long time at around 100K, peaked back at 400K and is now around 200K

SDC has been on first page of trex for as long as I can remember while XMR doesn't want to leave last page
SDC main exchange is Bittrex, XMR main exchange is Polo. Their relative positions are reversed on the other exchange.

SDC folks don't spam altcoin discussion section while XMR is creating thread in hourly basis and go as far as telling me that it's going to beat BTC (that's a big turn off since I'm early adopter of BTC and honestly don't see comparison)
that's all.
I don't know about the SDC launch, I wasn't there.
The SDC distribution process of 100% of the supply going out in two weeks is terrible.
The Monero launch was fair, and the distribution process of 85% of the base supply going out in 4 years, with a 0.3 XMR (0.9%) disinflationary perpetual reward after about 8 years is a bit fast, but defensible.
Technology-wise they are somewhat comparable as the SDC anonymity scheme is based heavily on cryptonote. The SDC code base is largely based on Bitcoin, via Blackcoin or some other path of forking (I'm not sure of the details), so part of it is more mature than Monero, although the anon part is newly implemented and probably less mature.
The cryptonote alleged improvements on Bitcoin that aren't anon-related such as dynamic blocks sizes are not present in SDC, so that would be a point for Monero if you think those are good.
That SDC has an integrated non-anon portion of the chain could be viewed as a privacy negative since it will pull some of the transactions out of the anonymity set. Monero is going in the other direction pushing all transactions into the anonymity set, although that isn't implemented yet, so Monero also has a non-anon portion of its chain currently.
EDIT: I agree with fluffypony's later point that proof of stake is cryptographically unproven and likely unsound and unfixable.

Disclosure: I have a stake in Monero, both in the community and financially. Despite that, I attempt to impartially start this topic of debate between these two privacy-centric currencies.
I am interested in anonymous cryptocurrencies, and Monero and Shadowcash both catch my eye (as well as BoolBerry, luv u 2). Monero we have probably heard a lot about in recent threads, but I will recap some basic stats of both currencies. I present ShadowCash first as a gesture of good will:
And Monero's specifications:
I am not sure the world is big enough for two totally successful anonymous cryptocurrencies. Each new ultra-successful crypto will present something fundamentally new and valuable to civilization. That is the only way they will rise to dominance. We saw this with Bitcoin already, and I humbly submit (as my personal opinion) that a truly anonymous cryptocurrency will be the next crypto to break and hold the $1-billion dollar marketcap with significant volume.
Of these two, which one has the superior technology, better distribution scheme, fairest launch, and most potential going forward? I will not be commenting on this thread with my opinions because I have bias and would like to hear some opinions from both sides. I'm hoping the ShadowCash supporters and developers will take the time to come and discuss their currency with us, and we can have some of the long-time Monero supporters and devs comment as well.
