Was E50K most of 2017 and got early recognition for E75K, and eventually went over 100K AQM and $20K AQD in December, so will be SE100K in 2018. Based on my past experience, I don't personally think that there is enough of an advantage to go for E75K since E50K gives you most of the same advantages. I found some improvement in my eup lottery chances (due to the 2-day earlier booking window) but otherwise little advantage for that kind of money. If I was E35K trying to get to E50K, I would say go for it, same for E75K trying to get to SE100K, but E50K trying to get E75K - I'd turn that down. My own personal opinion is E75K doesn't have much advantage over E50K..
