If money is an issue than yes, go with the Remington. If not, Definitely a Surgeon. Custom actions are just that, custom. They are about as near to perfect as an action could possibly be. A trued Remington is a great action and very accurate when done right, but it will never take the place of a custom precision action, period.
There will be folks who will say that their factory blue printed Remington 700 action will shoot just as good as a Surgeon. Maybe.
I have a Surgeon and it will put a five shot string in the same hole every time. I also have a blue printed Remington and the best I can get out of it is .4-.5 clover leaf. Don't get me wrong here. A blue printed Remington action is nothing to frown at. They are highly accurate and a very great action. After all, if you look at most custom actions out there, like the Surgeon, they have some similarities to a Remington 700.
Surgeon's, for example are cut one at a time. The tolerances are exact from one action to the next, the cuts are as close to perfect as a CNC Machine can make them, and did I say they are built one at a time. Remington factory actions are built on an assembly line, sometimes by folks who are just there for a pay check. So no matter how much truing one can do to a factory Remington the precision is just not on the level of a custom. Thats why a brand new Remington Action sells for around $450 - $500 and the Surgeon sell for $1200+ and many other custom actions likewise.
Buying a Surgeon Rifle is like buying a small vehicle. They are not cheap. They are one of the highest priced guns on the market today. I have a small fortune tied up in my Surgeon Scalpel. So if money is not an issue, sell the Remington and call Surgeon and sit down with them and design what you want on your Surgeon and then let them build you one. I promise, you will not be disappointed. Comparing a blue printed custom Remington to a Surgeon Scalpel is kind of like comparing a Cadillac to a Bugatti Veyron.
