What is the difference between Mario and Doctor Mario?

In Super Smash Bros 4 (and other Smash Bros Games), both Mario and Doctor Mario are playable characters. But, besides the alternate looks and the different Down-Specials, are there any other differences?

Solution 1:

According to the Super Smash Bros 4 wiki:

While Mario continues to use his updated moveset from Brawl, Dr. Mario retains the old Melee-style moveset, albeit with a Final Smash now. The Final Smash is similar to Mario Finale, but instead uses enormous Megavitamins rather than fire.

There are also several differences between them. For example, Dr Mario is:

• Stronger than Mario
  • Having higher damage percents on moves such as up tilt, up smash, back aerial, up aerial, forward tilt and all throws.
• Slower than Mario.
• Does not jump as high as Mario
  • Also has a lower air speed.
• His Doctor Finale deals more damage than Mario's Mario Finale.
• His Jab Combo deals more damage and knockback than Mario's.
• Dr. Mario's Dr. Sheet doesn't stall him in the air like Mario's Cape does, and has less horizontal range.
• Dr. Mario's Down throw has more knockback than Mario's, which allows for different followups.
