These tours are very similar.
In order to do all four sites, you spend a limited time at each one and it is a long day in the bus.
I did the Egged tour. We had an excellent guide. Not so impressed with some other members of the group but that happens anytime you get a group together. It was a really long day. We spent more time in Akko and almost no time in Haifa, only long enough to stop and take pictures from the top of the gardens down to the port. However, the time at Ceasarea was excellent, but rushed, the time in Akko was excellent and Rosh Hanikra was fine.
I would not exclude Egged from the list. Compare group size (our Egged tour only had 10 people), price, and length of the tour.
Although I didn't do other companies, I have seen the groups coming and going from the sites (especially at Ceasarea) and they are all very, very similar in what you see and do.
