Stroller, car seat, carrier, ect

I'm really struggling with picking the right stroller, car seat, carrier, the whole thing. I love the Graco 4Ever because I can get long term use from it, however it isn't a travel system (if I've read correctly.) I've seen a few, such as Graco Pace Click Connect, Graco Fast Action Fold Click Connext, Graco Verb Click Connect, but I'm really lost as to which one is the "right" one. Please help! 😫😓
