The upside is that Remington realized its mistake in the 710 design. The 783 is definitely not the BIC rifle the 710 was. The only thing that would cause me to pause would be how relatively recent the rifle is. It may stay for a while - perhaps even a decade - but until it has been out long who knows how much product support it will garner. The same can be said about the other rifles on your list except for the Stevens. The Mossberg is starting to get good market support, the others may or may not reach that point.
The trouble is that all the companies listed have introduced budget rifles in the past and then orphaned them. Marlin had the superb MR-7 but dropped it almost as fast as it introduced it. With Remington, the 788 and 798 rifles were good, but the 788 got dropped as soon as Savage dropped the 340 and Mossberg the 800. Budget rifles tend to be designs that last for a while but never get beyond the companies' periphery.
The only rifle on the list that is not the bottom-feeder in the company line is the Mossberg (okay, the ATR is the bottom, the 4x4 is not, but they are the same actions). Mossberg has but one centerfire rifle design, so what you get in that offering is all they got. If they plan on staying in the centerfire rifle business, that is what they have to offer. They once had the solid 800, the superb 810, and the great Howa 1500 but let them all go. The ATR has survived almost a decade, how much longer? If Mossberg remains competitive, perhaps a long while. It is their best bolt action centerfire rifle, after all.
The 783 is likely a decent rifle - all the rifles on the list copied Savage's 110 design features, some more than others. The only problem I see (other than potential design issues that lead to a recall - something common on newly-introduced firearms) is that you won't be able to do much more than shoot the rifle for a while until the support market is convinced of its staying power. How much that will matter depends on you. It will shoot and will probably shoot accurately, which is all you have to ask of a rifle.
