I think Samus is easily a top ten contender. Dunno why you'd place her anything short of that. She has everything going for her except a top tier combo game, which is hardly necessary when you can still do 40+ damage anyway and knock them far enough away that you can set up your god tier camping and zoning game.
Missiles still cover crazy amounts of recovery options even against some of the best recoveries, she has the best pokes outside of the swordsmen and maybe m2/ddd, not counting Zaïr which pretty much outclasses all other pokes. She has the most mobile and lowest crawl invalidating a lot of aerial approaches and other projectiles, and an amazing crawl attack that make cross up on shields so much more possible while complimenting her already great CQC poking game on shields.
And then you have ice beam, for handling those pesky airborne opponents and recovering enemies. Not that she really needs it that much, because her fire beam got buffed anyways with better linking hits on fair and usmash, plus upair has bigger an better linking hitboxes too so now it actually beats opponents coming in from high.
Bombs are also unblockable in PM btw, she can land them directly out of a footstool, which she can do directly out of a SH dair.
Also grab is faster and pivot grabs are a thing so it's not completely unreasonable to land one anymore, and with great dthrow follow-ups on most characters it's guaranteed damage into stage positioning which is, again, setting up for missile camping and general zair/tilt zoning.
