Totodile still isn't the best of choices because it still suffers heavy competition from Corphish, which isn't top tier to begin with (although Corphish is still quite good); however, you're right in saying that it's no longer totally outclassed, because it is now able to effectively get around Foongus and Cottonee. Swords Dance is arguably better than Dragon Dance because Totodile is much weaker than Corphish, so it needs all the power it can get; Aqua Jet is powerful enough to OHKO a number of very frail Pokemon at +2 regardless, provided Stealth Rock is in play. With that being said, Dragon Dance still has its own advantages. Eviolite is generally the preferred item because even with Life Orb, Totodile struggles to OHKO Eviolite holders, and is outsped by most of the offensive metagame which can then proceed to prey on its unboosted bulk, meaning it isn't too threatening before set-up; Eviolite grants Totodile the bulk necessary to safely pull off a Swords Dance or Dragon Dance. The analysis currently has 16 Atk because the difference in damage rolls between 16 and 17 Atk is minimal for non-Sheer Force Totodile so the point is better invested in bulk, but Sheer Force changes this, so the analysis should be updated accordingly. Don't fret about asking questions, because we have SQSA for a reason :)
