Pros:
-Considered a carny game, most places don't even look for card counters in this game.
-Advantage increases by more per TC than in blackjack.
Hence it is easier (and prudent) to get away with a large spread.
Cons:
-Due to more complex rules, this game is harder... The basic strategy is more complex, and it is worth it to memorize a ton of indices as more of the advantage is gained by index plays than in blackjack.
-Oh, and there is alot more information readily available for blackjack... It's been around longer, studied more from various points of view.

I also don't necesarily agree with the comments that SP21 is lower variance. Certainly the version I typically play (which allows double-double down) is higher variance. The result of several of my sessions comes down to what happened on my max bet redoubles, and I see much wilder session results and bankroll fluctuations with SP21 than I'd ever seen with BJ. I'm not as familiar with the S17 game, but recall hearing that even with it, you double-down more frequently than you do in BJ. That alone would increase your variance.
A couple years ago, this may have been accurate, but it's certainly not the case today, now that a book has been published and there are several ridiculous claims that the game is "better" than blackjack.
There may be a few places at remote locations who will leave you alone on Spanish, but in areas where the game is readily available, you're just as likely to get counter-measured and/or backed off SP21 as you are on BJ. More than half of my backoffs in the past couple years have been on SP21. The idea that you can blast away aggressively and get away with it is simply no longer true.

About the only benefit to learning SP21 is to give you more options. If you live in an area or travel to an area frequently which has a lot of SP21, it might be worth the effort to learn the game. If you're not able to play the game on a regular basis, I'd look for other opportunities.
You are most likely referring to the Atlantic City game, where your expectation is better than at Blackjack, especially H17.
I have drawn major heat [betting light green] at several casinos in A.C., but that may be primarily because I am "persona non grata" almost everywhere.
Most people receive no heat it is true and larger than normal spreads are tolerated.
according to wizard of odds, House edge 0.40%, S17 base on
dlr has hole card?
will dlr peek n open immediately if it is natural?
player loss all DD/ split to BJ?
how the H.E. increase if not allow to hit for splitted Aces?
That has been changed. A complaint was filed with PA Gaming, and they agreed that multiple hits must be allowed on split aces in Sp21. If you were there in the last 2 weeks and it hasn't been changed, contact gaming and remind them.Mohegan Sun Pocono also has the single card to split aces rule.
Does anyone know the house adv. of the Spanish 21 game at Foxwoods ??
