Ironically enough, the vanilla version of this port is the worst way to play this game. You may be wondering, why do I still recommend it then? Simply because of BetterSADX

This will fix the issues the PC port brought, an option to use either the DX or Dreamcast models, Discord Rich Presence, restore features from the previous ports and the OG Dreamcast version, and so much more.
The other best option for playing this game is to play the original game on a Dreamcast or emulate it, which is a bit of a hassle and/or pretty costly. Unless you're that much of a diehard fan.

I still highly recommend this game if you're either a long-time fan of the series or a newcomer who wants to play what many fans may consider one of the best in the franchise.
I completed this game on my birthday in 2023, and it became one of my favorite games of all time. I also can't help but cry every time I listen to Azure Blue World

Use BetterSADX when playing it.

Honestly, one of the best Sonic games I've EVER played.
The music is pretty good and catchy, the gameplay is fast and awesome, it's such a cool game you should DEFINITELY try if you're a Sonic fan.
If you don't like how the DX version handles things, you can use the SA Mod Loader. (I honestly don't have any issues with the DX version, it played flawlessly for me, and I enjoyed it very, VERY much)
Basically: you should buy the game, if you want a pretty good Sonic 3D game in your collection.

While this game may not have aged well in many aspects I still think it's absolutely awesome! This game oozes Dreamcast charm and is very experimental compared to other Sonic games, with the game in general being pretty fun and having a damn cool story.

Don't go in expecting an incredible experience, as you will be disappointed. This game is very flawed but those flaws are what makes it so charming and special to me!
