Juan, I have just started using the 2017 Apollos. So far, I've spent time using the 12m and the 9m. I have a 7m that I haven't had a chance to use yet.
The Apollo is comparable to the Ozone Edge. They are both extremely high aspect LEIs that are good for racing and foiling, among other things. I agree with Dylan that, for racing, they probably can't keep pace with the high aspect race foil kites now on the market. But for hydro-foiling, they have the advantages of being inflatable (for some, this is an advantage) and much less expensive than ram air kites.
As xoen says, they are also great kites for boosting, hang-time, and airstyle. That is why I chose them, and I haven't been disappointed. The hang-time is significantly better than other LEIs I've used, and I can easily loop these kites (including the 12 m) as aggressively and quickly as my "faster" LEIs. The 7 m will not be a slow kite, if only due to its small size.
So if you want to focus on boosting, hang-time, old-school (and possibly hydro-foiling at some future date), the Apollo is a good option, especially at current prices. I've found that these kites have a surprising degree of stability in gusty conditions, they re-launch easily enough, and they have a lot of wind range. I would not recommend the Apollo to someone interesting in wave riding or unhooked wakestyle, but for the limited purposes listed above, you'll be happy with one, IMHO.
