Sultanahmet vs Kadıköy
This is the rare Istanbul comparison where the two neighborhoods aim at completely different trips. Sultanahmet is sights-on-your-doorstep, Sultanahmet-or-bust. Kadıköy is the Asian side — no major sights, the city's best market, the version of Istanbul that repeat visitors fall for. The honest answer for first-timers is Sultanahmet; the interesting answer for second-timers is Kadıköy.
The historical peninsula — Hagia Sophia, Blue Mosque, Topkapı Palace, Grand Bazaar all walkable. The first-time-Istanbul default.

Major historical sights
SultanahmetSultanahmet wins, decisively. Hagia Sophia, the Blue Mosque, Topkapı Palace, Basilica Cistern and the Grand Bazaar are all walking distance. Kadıköy has no comparable sights — you'll ferry across daily.
Food market
KadıköyKadıköy wins decisively. The market around Güneşlibahçe Sokak is the best food shopping in Istanbul. Sultanahmet's market is the Spice Bazaar, which is tourist-managed and significantly more expensive.
Local life
KadıköyKadıköy. It's a working Istanbul neighborhood with cafés that aren't tourist-priced, residents who live there, and a ferry-commute culture you don't see in Sultanahmet.
Price
KadıköyKadıköy hotels run 30-50% cheaper than equivalent Sultanahmet product. Dinner and drinks are 40-60% cheaper. The savings on a longer trip are substantial.
Daily logistics
SultanahmetSultanahmet wins. Kadıköy means a 15-20 min ferry across the Bosphorus to anywhere historical. Ferries are reliable and pleasant, but they shape the day.
Best for first-timers
SultanahmetSultanahmet. If you have 3-4 nights and a sights-heavy itinerary, Kadıköy adds 30-60 min of ferry time per day to your trip. That's 2-4 hours over a week.
The verdict
Pick Sultanahmet if…
Pick Sultanahmet if it's your first Istanbul trip, your trip is built around historical sights, and you have 4 nights or fewer. The location is the trip.

Pick Kadıköy if it's your second-or-later Istanbul trip, you've already done the major sights, you want a meaningfully different version of the city, and the daily ferry commute sounds appealing rather than annoying. Repeat visitors who book Kadıköy almost never go back to staying in Sultanahmet.

Sultanahmet is the sights trip. Kadıköy is the lived-in Istanbul trip. Try Kadıköy on your second visit; it changes how you see the city.
