For novice players who also play for fun, I would recommend playing the game that you like best, and not to worry about economic considerations. We should try Texas, Omaha, and other games and stop at what we like more.
If the goal is to earn money by playing, then it seems reasonable to me to choose the game in which the analytical corpus is developed the most today. This is due to the fact that it is in this part, unloved by the players — the analytical part — that a guaranteed advantage over the "sloths" lies. Probably, I would still prefer Texas. Although, admittedly, Omaha has also been actively developing lately. In general, paying attention not only to Texas, but also to Omaha is true. And from the point of view of great gaming prospects, and from the point of view of ... a kind of gaming stereo thinking.
