Canon's SL-series compact DSLR cameras are some of our favorites for underwater shooting. All cameras in the series provide outstanding performance in a super small, lightweight, and affordable package.
Here's a breakdown of what changed between the release of the Canon EOS 200D Rebel SL2 and the newer Canon EOS 250D Rebel SL3 (also known as the EOS 200D Mark II or Kiss X10 camera).
Similarities
Both cameras feature the standard Canon EF/EF-S lens mount and were released as kits with the Canon EF-S 18-55mm f/4-5.6 STM lens. Each has a fully articulated 3" rear LCD screen and optical viewfinder. The cameras use SD/SDHC/SDXC cards and feature built-in wireless with microphone and mini-HDMI ports.

Housing Compatibility
Canon re-designed the flash hotshoe which shifted everything on the camera body down slightly, most notably the lens. This change prevents the newer EOS 250D Rebel SL3 camera body from operating in existing housings for EOS 200D Rebel SL2 or EOS 100D Rebel SL1 cameras.
The new hotshoe also prevents the use of manual strobes with the camera. A built-in TTL converter in the new housing allows communication between the camera and most Ikelite DS strobes.
Conclusion
You won't go wrong with either of these systems underwater. The newer EOS 250D Rebel SL3 has the advantage with about 65% more battery life, more autofocus points, and the ability to record in 4K video resolution.
