I am a Massachusetts native myself! I miss the South Shore!
Knowing now where you are riding, I can provide even more advice. I truly don't think you can go wrong with any of these bikes. In terms of suspension and knowing the types of trails you will be on, I honestly don't see full suspension as a priority.
I will put a plug in for the Co-op DRT 2.1! I like this bike a lot and really enjoyed riding it last year up in Vermont on the Kingdom Trails. The dropper seat post was a nice additional feature on this bike!
Hope this helps and you are hitting the trails soon!
