The answer is NO.
If you look at the number of transactions done per day for Monero it's pitifully low - 4,624 in the last 24 hours:

How many people on here use it as their primary cryptocurrency? And if you are not using it, why do you expect others will use it?
Cryptocurrency is still very young and difficult to use; heck, most people I talk to still have'nt heard of Bitcoin much less the alt-coins. Developers are currently trying to make it easier for the average person to use Bitcoin and alt-coins.
Coinomi is a mobile wallet that is going in that direction. There was a review of coinomi just a few days ago on 99bitcoins and here is a direct qoute from that article:
"The biggest reason the Coinomi user base continues to expand is due to the enhanced privacy they offer with their service"

This aspect of the crypto space is going to get very big.
As for which privacy coin is better:
Zencash is Zcash with improvements: Zencash will have Secure Nodes in about three or four weeks making it very unuiqe among privacy coins. It will also have encrypted comminications. Also, someone is already running 5 dedicated nodes over the Tor network for added security.
Obviously, I'm a big Zencash fan and think it will have explosive growth over the next 4 months, but I also think all of the privacy coins will only grow bigger in the forseeable future.
