Burger King Coffee vs. Starbucks

Starbucks coffee is significantly stronger in caffeine content and bolder in taste than both Burger King and McDonald's. [1, 2]

Caffeine Content Comparison (Brewed Coffee)

Starbucks standard drip and blonde roasts pack roughly double the caffeine per ounce compared to fast-food options. [1, 2]

Starbucks (Grande, 16 oz): ~310 mg to 330 mg of caffeine (Pike Place or regular drip; a Venti 20 oz hits ~410 mg, and a Venti Blonde Roast hits 475 mg).
McDonald's (Large, 21 oz): ~185 mg of caffeine (Premium Roast).
Burger King (Large): ~169 mg of caffeine (using Seattle's Best blend). [1, 2, 3, 4, 5]

Flavor and Strength Profile

Starbucks: Uses a heavy-handed, darker roast profile (like Pike Place) or high-caffeine light roasts, which many coffee enthusiasts and taste tests describe as intense, bitter, or heavily charred compared to fast-food averages. [1, 2]
McDonald's: Uses a 100% Arabica medium roast designed to be smooth, mild, and accessible rather than aggressive or bitter. [1, 2]
Burger King: Serves a milder, average-strength medium roast (historically tied to Seattle's Best) that leans toward a lighter, easy-drinking fast-food profile. [1, 2, 3]

I occasionally get a large Burger King coffee.  I think that it has a good taste.

At home I've been cutting back on my caffeine intake by mixing regular coffee with decaf, because I've noticed that coffee can cause my heart rate to stay high for a long time.

Multiple sources state that people over 60 take longer to process and eliminate caffeine from their system.  I only drink it in the morning and I like the boost I get from it.

BTW, tea bags and cans of diet soda are typically only around 45 to 50 mg of caffeine.
