Who is the better opponent between these two? Which one would be a more prestigious win for a fighter's resume?
Ortiz is better than 2020 Pulev let alone 2021 as far as i can tell, but if Ortiz looses to a borderline Journeyman like Martin I'll rethink this.
Pulevs done far more with his career than Ortiz, but that's not difficult. It could be an entertaining scrap between the two, though Pulev would win more often than not IMHO. Ortiz is much more highly hyped, so in terms of convincing casuals of the strength of a resume it's probably Ortiz... But in truth, Pulev would be harder to beat, I think.
