Both are superb amps for your application. The 750/1 is indeed a one channel MONO amp and will deliver slightly more power BUT you will have to connect your four speakers in series/parallel. The 600/4 is a 4 channel STEREO amp and requires straight forward wiring...each speaker has a dedicated channel.
There is an excellent article at Earmark Marine's website which compares the two. with 4 speakers so close to each othe the stereo effect is for all practical reasons null and void. Some guys strongly oppose this idea...
