The short answer
Compare actual models and complete lens kits. Mirrorless uses an electronic viewing system; a DSLR offers an optical viewfinder. Features, size, battery use and prices depend on the equipment and shooting mode.
Reasons to compare mirrorless models:
- Electronic exposure preview
- Potentially compact body options
- Model-specific subject detection
- Video features that meet your needs
- A suitable lens and support ecosystem
Reasons to compare DSLR models:
- Optical-viewfinder battery efficiency
- Used body and lens prices
- Handling and build of the exact model
- Compatible used lens options
- Excellent value on used market
