Screen space
The 15.3-inch display has about 26% more pixels in total (2880×1864 against 2560×1664), which makes side-by-side windows, spreadsheets and timelines more comfortable. Both are 500 nits. If you often work away from an external monitor, the larger screen is the main argument for the 15-inch.
Portability
The 15-inch weighs 280 g more and is noticeably larger in both dimensions, which affects bag choice, airline tray tables and lap use. The 13-inch is the better choice for students and frequent travellers.
Performance and battery
Both use the M5 chip; Apple lists the 15-inch with a 10-core GPU as standard, while the 13-inch starts with 8 GPU cores and offers 10 as an option. Apple claims up to 18 hours of battery life for both; the larger chassis does not change the claim.
