For me;
Board The Platforms > Individual Break The Targets(Pichu's aside, that goes into bottom tier) and Grab The Trophies > Angry Brids Targets(3DS) > Generic Break The Targets > Angry Birds Targets(Wii U) > Home Run Contest > Coin Launcher > Break The Pichu
I like all versions of Race To The Finish, though the order for me is 64 > Ultimate > Melee. Melee's just feels too long and kind of boring compared to the others, which are filled with life. One thing I like to do, via a Gameshark/etc. is have infinite time on 64's RTTF, or even use it as a full stage. It gets crazy how far characters get sent flying and is loads of fun. I think the only downside to the stage at best(besides Master Hand unable to function at all on it) is the lack of items. I forget if that was a thing. It's been a while. I also can sometimes just watch enemies play on it via my emulated version, and it's just hilarious(unfortunately, they're terrible at trying to recover, so it stalls sometimes. Thankfully Giant DK is a nice choice to keep everyone in the fray).
Damn, I forgot a lot of modes. Most of these were Classic Mode, but I did enjoy Smash Tour(just needs more ways to control your choices), Smash Run was fun, Event Matches were fairly good in Melee and Brawl, but I found 4's kind of eh at times. Master/Crazy Orders was neat, though. I've enjoyed all variations of Adventure Mode(Smash Run I'm counting as a bit more of a side thing, as it's clearly based around a similar idea, but isn't meant to be basically a Story Mode like the Adventure, SSE, and WoL are. Not to say Melee's is a "good" story, but it's still there). While I'm at it, I liked All-Star the most in Melee. Brawl's wasn't bad, just not random enough. 4's got too long and annoying for me to want to complete it. Even Brawl's had more breaks between the fights, as unbalanced as it is. It'd take a long time to explain Classic and which ones I liked/disliked. >.<
