The age old question.
I’m one of those old length first guys (from theory and gut, not practice), but there are many that have good arguments for otherwise. Example, some will recommend bouncing between both longitudinal and latitudinal stresses for strategic periods of time. The idea here being that overall expansion must be achieved in both directions to optimize growth potential. I hope they are right because this is my natural PE tendency, not for reasons of logic, but rather just emotional as I love experimenting with all forms of PE and I get bored.
At the end of the day, I believe the best PE routine is the one that keeps us practicing the most consistently and safely. For each of us that story is a bit different.
I say condition with the old classic, the jelq, then maybe move on to an extender (not right for everybody).
Be safe, have fun, PE today and tomorrow.
Big gains to us all!
