if your such a superfan then you know G8 a filler arc is worth watching. and has even been semi canonized getting a mention in Episode of Merry.
The anime is fine if you like what you see you make make your way through the manga later it's a good adaptation and dispite what every onepiece autist will insist some cannon arcs are more or less irrelevant aside from one or two bits which will definitely be flashed back to. (you can skip skypiea entirely and miss almost nothing except an admittedly sick fight scene that takes way too long to get to)
It is a nice fun story. It's not bad to watch but nowhere near the hype many advocates put into it.
Also anime can't canonize anime. It's the same as saying it got canonized by the appearance of the commander during the war of the best. It is not cannon in any way.
And insisting skipping skypea is doable just tells enough about your (missing) understanding of the world... But that's neither here nor there. I stop the detailing now.
