Where to start?

I just got Marvel Unlimited, and I'm overwhelmed by the options! Can a seasoned comic reader tell me where to start?

I'm a huge Spiderman fan, anything avengers. Just lost on what to start reading. I read the first issue for secret wars and feel like I'm missing a ton of context!

Edit: thank you for the suggestions everyone! I'm starting with Ultimate Spiderman! I got a bit list to get through now!
