The MK Hype™

Oh, probably not Ninja Hideaway either, or Coconut Mall all things considered, but the rest do look a lot better. It's probably because Choco Mountain is kinda empty detailwise, minus the cave.
Atleast the Tour version made it look like chocolate, unlike the N64 version which looks like poo.

Is Mario Kart 8 Deluxe worth getting if I have the Booster Course Pass?

Tokyo Blur : widened
Paris Promenade : Road is better
Ninja Hideaway : pretty obvious, more life and a better color palette (fixed shades)
Shroom Ridge : we didn't got the circuit in MKT yet (even if it was in the files of Tour)
Coconut Mall : same as Shroom Ridge
Toad Circuit : better color palette for the sky setting imo (it's clearly sunsetish in MK8DX version, but it looks like 2PM in the MKT version. Confettis on the start, more detailed road, MKTV car and some audience in the tunnel.
Sky Garden : way better color palette (it has a better and more cool road, more complex shading on the clouds, better sky (the MKT sky was ugly), and there is even some grass on the road. Also the leaves are way better in this new version.  
Choco Mountain : lightened up with more textures

Actually it's either Tokyo or Choco Mountain to me.

Wouldn't having the Booster Course Pass be useless without 8DX?

I mean, those are pretty normal things to change for 8DX.

I don't have either one. I'm asking if they're worth getting (I have MK8 and all the DLC for it)

Well, I would think so. Unless you'd rather wait until 2024 for the next console & MK.

Yes but they didnt did enough on Choco Mountain

Am I the only one that doesn't like Ninja Hideaway's music

No, I don't know anyone else besides you, but someone must not, that's how things work. I know a couple people more attached to the Tour version, but they are fine with this version. Tour music is awesome, you should listen to all of the Tour OST.
Though to be fair, your opinion is yours. I know I'm the kind of person who listens to the 30m rips on Youtube the whole way through, but if you don't like it, that's up to you.

What does N64 have over GBA? & GCN over TOUR? In your opinion.
I get that GBA is very 32 bit, but what about GCN?

To me, GCN is over Tour. Like the circuit theme is very catchy and classic, Peach Beach/Daisy Cruiser sounds very chill and tropical, Baby Park sounds like a carefree chaos etc. The city music is really good too, the Rainbow Road, the forest theme as well. While for Tour, it's not so bad. Some of them are good and I really love Vancouver Velocity... While Singapore Speedway sounds horrible to my ears, and Los angeles Laps is even worse. I'm also not a fan of Sydney Sprint.

I can understand Singapore for some people, but Sydney?
Also, Bowser's Castle & Dry Dry Desert are pretty bad in GCN. Tour's lows are higher than GCNs.

Yeah they are pretty bad. But that's still better than weird people shouting or "singing" horribly in Los Angeles Laps' one, or hearing chipmunks with a horrible nightclub sound in the background.

So basically, your problem is the voices?

I know what he means.

So people from Singapore sound like Chipmunks?
And there is another version of the song.

And the problem : they sound like horrible chipmunks. This comes from a person that enjoys this effect and who can't hear some songs if they aren't nightcored. So yes.

I do
