I guess it depends upon how you want to qualify "better", tho the 30-30 and .44 will shoot through fewer numbers of adjacent homes than an '06 if ever used for defense around the house, so that may be something to consider depending on the proxmity of, and your fondness for, your neighbors. Both the 30-30 and .44 pack plenty of power at modest distances for most defense scenarios.
I have both a Marlin 336M (the stainless one) and a 1894P .44, and I like them both immensely. The 1894P is smaller and somewhat easier to handle (makes a great car/truck gun as well), and the ports don't seem to add too much to the noise factor. The Marlin sights will have to go, tho; a peep sight arrangment is much better than the factory semi-whatevers they put on them, but both are solid shooters.
I have no experience with Winchester, but others will and you can find a good bit of previous discussion about the pros and cons of each brand if you search previous threads. Some say the Winchesters (at least the older ones) have a somewhat stronger action, but being able to clean the Marlins from the breech end is a huge plus IMO.
