If I had to choose between those, I'd definitely go with the Hitachi. 100MHz dual channel analog scope.
It uses standard 10X scope probes. You should be able to use some cheap generic ones like this:

Max DC voltage on the scope input is 500V so be careful. Don't go probing around the vertical output transformer or horizontal output tube.
You can get a free manual here.

I see it has dedicated TV-V and TV-H triggering modes. That may make examining video signals a bit easier..

Here's how I did a similar restoration in detail. But it was easier anyway. (these radios are much smaller and lighter)
