I have a mixed impression regarding these new providers. Sure, a wide supply of providers will lead to a healthy competition between them. On the other hand, I think (and probably, others will support my opinion) Microgaming, NetEnt, and Playtech will always be the best, as they already have strong positions on the market and many cool features. Many articles like this one http://uschnews.com/technology-behind-online-casinos-top-3-software-providers/ keep on writing how good they are, and players (especially newbies) should stick to them, IMO.
