Being an Anti-Sicilian vs. Sicilian player So I have been developing my opening repertoire on ChessBase recently and established that, as a 1.e4 player, I have to properly memorize Open Sicilian main line, Dragon, Hyper Dragon, Taimanov, Löwenthal, Kalashnikov ,Sveshnikov , O'kelly, Najdorf , and surely some others ones which I am missing.
Wouldn't it be better for me to just master one anti-Sicilian line like for instance the Grand Prix Attack ? Indeed, from the Lichess 2000-2200 ELO games database, here are the win rates associated with the opening 1.e4 c5 2.Nc3 d6 3.f4, i.e., the Grand Prix Attack

         

This looks like a pretty good weapon for white if you ask me and avoids having to memorize literally a constellation of lines in the Sicilian.

My question is, are there any benefits for me to carry on playing the normal lines of the Sicilian and undergoing all the required memorization or should I convert to being an anti-Sicilian player ? What are the pros and cons ?


Additional information in light of my question

I am not a Sicilian player myself as black
I intend on pursuing a mastery title in chess
I nevertheless like playing Sicilian lines as white
I like memorizing lines but I also want to improve my ELO as fast/high as possible
The first question that needs answering is the following: what is your current playing level? The Grand Prix, and other anti-sicilians as well, can be a good way to trip up some sicilian players at lower to intermediate levels, but once your level of play gets higher these anti-sicilians will start getting less and less successful; there is a reason why they aren't the main lines after all.
But there is another aspect to this besides the result-oriented one, and that is your observation that many of these anti-sicilians require less memorization from the white player than the main lines in the open sicilian. At lower to intermediate levels this can be a good thing, since it means you can spend more of your time learning to play the middlegame and endgame properly rather than being tempted into thinking that studying more opening theory will bring you great levels of success. Another positive aspect of trying these anti-sicilians out is that you may encounter some nonstandard structures that you enjoy playing; this can prove very useful when trying to get to know oneself as a player. One final positive point in trying these lines out is that they will give you some indications as to why the main lines are what they are.
I would say that since these lines don't require as much study to pick up as the main lines, there is no real harm in trying them out. But you have to remember that they are a far cry from a silver bullet to the sicilian, and you should keep a flexible attitude about your choice of opening lines. Don't lock yourself to one specific set of lines to use for the rest of your career at this point when you haven't even reached master level yet. If you want to reach master level there is a high chance that you will eventually have to strongly consider adding some of the main lines to your repertoire, but this is something that can be done later. (who knows, maybe you end up adopting 1.d4 in the future?)
Although I don't think there is any harm in trying out slightly less common lines, I don't think it's bad to stick with the main lines either. One thing that you have to be very careful with is of course the risk of over-reliance on concrete lines. Don't just memorize the main lines thinking that you've learned them properly; after all, once you're out of the opening there is still an entire game left to be played, and if you don't know how to play these resulting positions you might as well not learn any theory at all. To understand these complex variations properly you need to play them many times, preferably against strong opponents, so that you can gain an appreciation of why the main lines are the way they are. You will also need to be able to find the optimal ways of playing when your opponent deviates from the main lines, and I will say the following: this is way, way harder to do consistently than it seems, so I will once again urge you not to place the memorization of main lines on a pedestal.
It may seem like the things I stated in the previous paragraph suggest that playing the main lines requires far too much work on your part, but this is not something that I wish to convey. While memorizing some lines is important in the open sicilian, I would say that the amount you need to actually memorize is less than you may think. You can get by surprisingly well with a shallow knowledge of concrete lines if you begin your study by going wide rather than deep; learn the basic gist of the lines (i.e., try to learn the main plans in broad strokes), and start playing as much as possible so that you can see how the plans work in action. Naturally you will have to learn your lines deeper and more concretely at some point, but if you have a solid foundation based on experience this will become a lot easier. Also, if you have experience playing without knowing the exact lines, it will be easier to play once you inevitably end up in a position that you haven't studied before.
