There may be evidence that Macau's casinos industry is actually finally recovering. After five months of rising gaming revenues that had external events accounting for at least part of the gain, the Chinese gambling district posted numbers for February that indicate the rally is real.

Even better for the major global casino operators, Nevada also put up some robust growth last month, so let's take a look at Las Vegas Sands (NYSE:LVS) and MGM Resorts International (NYSE:MGM) as both resort owners have their feet firmly planted in each market. Because they offer different plays on the two gambling regions, one might be a better bet than the other.

High-stakes wager on Macau

Las Vegas Sands has piled the chips high on Macau, generating 59% of its $11.4 billion in revenues last year and 54% of its adjusted property earnings before interest, taxes, depreciation, and amortization. That's second only to Wynn Resorts (NASDAQ:WYNN), which derives almost 64% of its revenues and 62% of its adjusted property EBITDA.

MGM, on the other hand, generates just 20% of its $9.5 billion in revenues from Macau through its 56% ownership of MGM China, which also represents less than 17% of its adjusted property EBITDA. Even after MGM opens its new MGM Cotai resort later this year, the distribution of revenues and profits won't be appreciably altered.

A focus on domestic resorts

Instead, Las Vegas is where it's at for MGM as its nine properties there generated over $5.5 billion in revenues last year, or 59% of the total. It also has properties in Maryland, Michigan, Missouri, and New Jersey that account for another 16% of revenues, a percentage that ought to rise in 2017 as MGM only enjoyed partial-year revenues from the Borgata in Atlantic City after purchasing the other half from Boyd Gaming, and National Harbor in Baltimore that opened in mid-December.

It is also developing a new resort in Springfield, Mass., that should be completed by late 2018 and has a 76% stake in MGM Growth Properties, a triple-net lease real estate investment trust it created to hold properties like Mandalay Bay, The Mirage, Luxor, and Excalibur.

Sands, for its part, has but two casinos in Vegas -- the Venetian and the Palazzo -- that, along with its expo center, generated just $1.5 billion in 2016, or 13% of its total revenues. At $2.8 billion, Sands' Singapore resort, the Marina Bay Sands, delivered more revenues than its Vegas operations.

Still, with both Macau and Vegas seeing gaming revenues on the rise, they should each benefit, though by how much remains to be seen because there are lots of factors that could undermine both locales.

A slow boat in China

The problems with Macau are well known, stemming from Beijing's crackdown on luxury, gift-giving, and corruption that precipitated the 26-month decline the region is only now just clawing its way back from.

It does appear the mandate to rely less upon VIP gambling is gaining traction, though, as Macau's Statistics and Census Service says visitors who stay at least a night in Macau -- typically considered tourists -- rose 18.9% in January and accounted for 47% of total arrivals. We won't know February's numbers until later this month, but considering the big jump in last month's gaming revenues on the peninsula, up 18% year over year and one of the biggest hauls for a February, it looks solid, even if we need to wait until next month to see whether it was due to VIP baccarat or other mass-market games of chance.

The problem is, the Chinese government remains only tolerant of the wealth passing through Macau, and it occasionally flexes its regulatory muscle to show it still has an eye on the region. Recent changes to ATM withdrawals, arrests of foreign casino executives for allegedly advertising gambling on the mainland, and the new policy of fingerprinting all foreign visitors coming into the country may still make tourists and VIPs alike skittish about laying down bets here.

A desert fault line

Not that Las Vegas' rebound is built on bedrock, either. While statewide revenues were up 12% in January (the latest data available), helped along by a 14% increase from the Strip, it was the downtown casinos that enjoyed the greatest growth, with a 32% year-over-year gain followed by a 25% increase in north Las Vegas. Yet the Vegas area saw declines across the board in November and December, suggesting it's a recovery still trying to get its balance and may continue to come in fits and starts.

Both operators, as well as rivals like Wynn and even Macau-based Melco Crown Entertainment, are planning to spend big in Japan when that market finally opens to casino development. Everyone has said they're willing to spend around $10 billion or more to build up their operations in what could become the biggest, and maybe the most expensive global casino market.

Although Asian markets seemingly having the greatest catalysts for growth, because of the ongoing risks inherent in Macau and Las Vegas Sands' big bet there, I'd say the odds tilt in favor of MGM Resorts for having the biggest advantages where an investor can lay his bets down.
