Monero is a great coin. . It's particularly cool that they are so easy to mine. I've even seen web pages that had built in XMR miners on them.
I personally like XVG even though it's certainly taken quite a fall in price.
The Wraith protocol has been proven to work. It's even being supported by Pornhub, one of the largest and most successful pornography sites on the internet.
Spotify even has a page with 3,000 current votes on it wanting to support XVG as the cryptocurrency to pay for your music subscription with.
Having said that, these things are subjective. Everyone is going to have their favorite coin and it won't always be based on the best use case.
I like monero more for a few reasons. The total market cap of verge is so high, being 16.5 billion. Monero is now already used as default payment method on the dark web and for other uses. Verge has better marketing than monero but the real adoption is lower.
