Well I'll do a bit of speculation based on the characters I've mained/seconded
Marth: My main. Metagame almost exactly the same as it was in melee. That's almost enough said...minus those advanced techniques, but still beastly. I find his horizontal recovery somewhat...difficult, but if you still have a jump, you'll almost always make it. The shorter sword bothers me just a bit (I've been missing in wifis a lot), but it's no problem to get used it. Still combos well. A definite top tier.
Lucas: My other main. Lucas is fun :D. SHPKF approach is very nice. Upsmash isn't as slow as I thought, and very easy to mindgame into, with a HUGE hitbox that lingers a bit. Grabs are nice, bthrow always kills at high percentages. PKT is great when opponent loses his jump. Love his aerials. Fast, high priority. Absolutely in love with dair. Fsmash is fast and strong. However, he's pretty light, and could probably be beaten by space animals...and Marth. I'm sensing a mid-middle or high-middle tier.
Ike: My secondary. Pretty darn fast for someone who's so strong. Quick draw approach is awesome, and great for mindgames (well...for me anyway). Bair is fast. Practically any attack can KO. He would be my main...if only he could combo. Most combos I can get in are 2-4 hits, all, if not most, ending in Aether. Somewhat predictable, aerials besides bair are slow, but hard to shieldgrab if aerials are spaced. His fair is fast after it's out, and hits under him too. But dayum... IF ONLY HE COULD COMBO

. A definitely high-middle tier.
Falco: My other secondary. I kinda dislike the shinerang, but it's good to get out of some annoying combos. Pretty nice edgeguard too, though there are better options. I hate what they've done to his dair; Falco pillar is practically nonexistant, though SHdairs are still pretty effective. His new neutral A is awesome, good for damage, hard to DI out of. Can CHAINGRAB (<3). His aerials are a bit weaker, but not by much. I see him as high tier, but not top.
Pit: I'll start off by saying I hate fliers, since SHaerial approaching with them is just...weird to me, and I just find them...annoynig >_o. For this reason, he's not a main or a secondary. But even though he is a flier, I love Pit. Bow game is awesome. downB is good for those pests who try to chuck projectiles at you while they're trying to recover (take that!), and comes out/goes away fast. sideB is pretty hard to DI out of, and good damage racker. All aerials are decently strong, and lead into combos pretty well. Pretty strong smashes. Insane recovery. Potential for top tier, but a definite high tier.
So here's my list:
Top Tier:
Marth
*Pit
High Tier:
Pit
Falco
*Ike
Middle Tier:
Ike
Lucas
*: has potential
Darn you people who put Lucas in low tier >:o
