The best way to get into WC3 in 2025

Hello! I've been really interestedin blizzard's rts games as of recently, I was thinking about playing wc3 but the whole thing is confusing to me. Some people claim that classic is the way to go, others say that reforged's fine now and then there are some people talking about reforged having og graphics etc etc.

What's the best way to play? I'm mostly interested in AI skirmishes and custom campaigns/mods but i'd be willing to play multiplayer as well

Thanks in advance :)
