Lethal - Yes it's the same. You can read the terms and conditions to find out.
Neemo - Yes, switch has slightly better odds and less variance, but I've found that for the time it takes to memorize the new basic strategy (hitting 13 and 14 against a 2, hitting certain hands you would normally double...) and to know when to actually switch the cards, it may not be worth it. I learned the strategies, spent a lot of time practicing and can do it all pretty quickly and I think I still prefer to play regular BJ.
