I recently recorded a "session" with two cameras. So each camera shows the scene from a different perspective, i.e. an a and b roll. I'm looking for an easy way to cut/disolve real-time from a to b as if it had been switched live. It is very difficult to break everything into clips and stay in sync. Any thoughts would be welcome.

While it is primarily designed for editing from clips, it will easily ingest each camera shot as a long clip.
Find an identifiable sync point in both shots (video or audio) and use it to apply both clips to the timeline beginning with the 'matched' frame. One of the clips will be on the primary (V1) video layer. The next clip will be on the video track 'above' the primary (V2) layer.
Scroll through the timeline while viewing the V2 layer. When it's desired to switch to the other (V1) camera, simply set "in" and "out" points and delete the highlighted section of video on V2. Be sure to use the "lift" or other equivalent function... NOT "cut", as you do not want to 'sandwich' the remaining pieces together! Do this all the way down the timeline. If you become quick at it, you can actually edit your video in less than real time, as it's not necessary to sit and 'watch' it all while making the cuts.
As long as you do not 'move' any of the clips from their original position on the timeline, the sync will not be disturbed.
Afterward, you can change the cut points to dissolves or any desired transition.
You will only need the audio from one of the cameras, so delete the other audio track.
I have edited weddings and other real time events this way where two or more cameras were used to capture the event. Many TV talk shows are actually edited this way rather than directed 'live', as it can allow quicker access to shots that a live director may have been late getting to.
When you are done, you can play the edited timeline in real time for recording to an output source, or render it to DVD or other file.
