Split vs Prague for couples trip (can't decide)

Hi! My partner (32M) and I (31F) are stuck between two very different trips and can’t decide. We’re looking for a getaway for wandering / walking around, good food + wine/beer, pretty surroundings, slow mornings with interesting days. We're not too particular (or decisive) but love a new city/restaurant/sites to explore etc. Both trips cost the same for us and have gorge places we're considering staying at, so that comparison isn't a big part of it. It's mostly length of time, affordability once we're there, and what's worth it this time of year.

Option 1: Prague (May 3–6, 4 nights)

• We’d be meeting friends there (but will also see them back home soon, so not a huge factor)
• Seems more to do and cheaper once there?
• Slight concern: wondering if it’ll feel more busy/touristy

Option 2: Split (Apr 26–May 1, 6 nights)

• Longer, more relaxed trip
• Old town by the sea seems lovely but is it too long for this city?
• Slight concern: been told it's not as visually “beautiful” as Prague/other cities + weather might be mixed

We were leaning for the longer trip in Split but are worried we might regret not seeing the "nicer" city with more to do.

Would love any thoughts from people who’ve been to either (especially for early spring timing).
