Fundamentally, which branch of a career tree would you like to perch on?
It’s not about now, or even (say) 2030, but beyond. A WSOp career is potentially relatively brief and certainly constrained (as noted above) in comparison to a WSO with prospects to age 55 and a decent pension thereafter. The latter also, IMO, offers wider career opportunities rather than just pure ‘specialism’, leading to a better CV if you decide to leave at some intermediate career point.
