Help to choose Corfu or Kos!

First of all, if this isn’t the place to ask that question apologies in advance..
Hey everyone!
My boyfriend and I are planning our summer vacation and we’re stuck between choosing Kos or Corfu. We’ll be traveling from Zagreb, Croatia, and we’re looking for a good mix of relaxing on nice beaches, exploring, and having good food/drinks in the evening.
We’ve done some research but we’d love some firsthand Reddit opinions to help us tip the scale.

We do not want to stay in an all-inclusive resort. Our plan is to rent a scooter immediately so we can explore the island on our own terms..

Thanks in advance for any tips, hotel area recommendations, or advice! 🇬🇷❤️
