Is the London system or Botvinnik English better for an attacking intermediate player looking for a

I'm an intermediate player who hates to play positions that I'm unfamiliar with.
I'm fine learning a moderate amount of theory as long as they aren't so rarely used (for example I won't learn 20+ moves of theory just to play against a trappy sideline that's only played less than 5% of the time) and I would like to have at least 80% of the time playing positions that I'm more familiar with.
I'm a fan of Simon Williams, therefore, I like to play in a sharp and tactical style, especially attacking the king, I'm ok being slightly worse positionally, but I hate to be on the defensive side.
Does the London system or the Botvinnik English suit me more?

Face your weakness and just play e4 or d4
otherwise you are missing out on 90% of what makes chess fun

English is hardly choice for sharp attacking style of chess. Any opening can turn into a sharp games. definately low on theory and due slow nature of game

Simon used to play english as a kid so why don't you check what variation he plays? If my memory serves it was botvinik one.

or look for more recent games with williams playing english as white

Though given your skill level sticking to e4/d4 and just developing you basic tactical middle games skill is far better idea. At you level probability that you run up against an opponent who knows some tricky sideline to move 20 is exactly 0. None of your opponents know theory past move ten and rarely even five so focusing on opening is not really that important.

@DanielZ42 Your recent game in the London System was perfectly fine (you didn't loose because of your opening choice) - you also seem know some basic "stereotypes" of the opening like the Bg3-maneurve, so it may suit your style.

Keep going!

I think you should try sharp Gambit openings like King's Gambit, Smith-Morra and the like. They often lead to very exciting games.
As black you can still play for attack with the Latvian or Elephant Gambit. They are considered bad on master level but to prove it on amateur level is easier said than done.

I doubt the London system or Botvinnik English are sharp openings. Thy seem to be the most positional and slow openings you can think of. And you will need a lot of practice to learn boring lines which will probably never occur in your games.

You could try the greco gambit, Evans gambit or the Scotch gambit as white. These are all pretty fun to play and not dubious.
Stay away from the London, it’s arguably one of the driest openings out there

The Jobava London might be a good fit for you. 1.d4 2.Nc3 3.Bf4

Depending on how Black plays, there's various aggressive ideas like playing an early Nb5, or h4-h5, or f3 and g4 type attacks

Honestly I never study any system, I could not tell you any opening name, and somehow I steadily improve over time.

But I heard that the king's gambit is a highly theoretical opening, especially the main line (3 ... g5) that isn't played so commonly at intermediate level right?
