there are actually 42 different mechanisms proposed for baryogenesis. the list is very interesting, so I reproduce it here

1. GUT baryogenesis

2. GUT baryogenesis after preheating

3. Baryogenesis from primordial black holes

4. String scale baryogenesis

5. Affleck-Dine (AD) baryogenesis

6. Hybridized AD baryogenesis

7. No-scale AD baryogenesis

8. Single field baryogenesis

9. Electroweak (EW) baryogenesis

10. Local EW baryogenesis

11. Non-local EW baryogenesis

12. EW baryogenesis at preheating

13. SUSY EW baryogenesis

14. String mediated EW baryogenesis

15. Baryogenesis via leptogenesis

16. Inflationary baryogenesis

17. Resonant baryogenesis

18. Spontaneous baryogenesis

19. Coherent baryogenesis

20. Gravitational baryogenesis

21. Defect mediated baryogenesis

22. Baryogenesis from long cosmic strings

23. Baryogenesis from short cosmic strings

24. Baryogenesis from collapsing loops

25. Baryogenesis through collapse of vortons

26. Baryogenesis through axion domain walls

27. Baryogenesis through QCD domain walls

28. Baryogenesis through unstable domain walls

29. Baryogenesis from classical force

30. Baryogenesis from electrogenesis

31. B-ball baryogenesis

32. Baryogenesis from CPT breaking

33. Baryogenesis through quantum gravity

34. Baryogenesis via neutrino oscillations

35. Monopole baryogenesis

36. Axino induced baryogenesis

37. Gravitino induced baryogenesis

38. Radion induced baryogenesis

39. Baryogenesis in large extra dimensions

40. Baryogenesis by brane collision

41. Baryogenesis via density fluctuations

42. Baryogenesis from hadronic jets

Any preference?
