It is very, very important that people be able to share their various opinions of what they like because this is how some of us learn. Sharing various trains of thoughts very often leads to Bruised ego's, which has happened here.
On another note, One of the main issues for me in having a custom rifle vs other less valuable rifles is pride of ownership. I feel as if "pride of ownerwhip" issue is a dangerous road to go down for a lot of reasons, Pride being one of the Deadly sins, not to mention tens of thousands of dollars involved, as I learned the hard way when a friend passed away and left me an old Ruger 77 Tang Safety 6mm Rem Varmint and a Parker Hale Mauser in 6mm Remington. I had Shilen Match barrels put on both, The Ruger in 243 AI and the Parker in 6 Rem with zero freebore. Both of these rifles immediately shot groups in the very low 2's, I was very humbled to say the least.
I now enjoy making a "Silk Purse from a Sow's Ear" idea, using Non Trued Rem 700's and Savages to shoot very tiny groups, and keeping as much money in my pocket as I possibly can. A custom off a Rem 783 and a Tikka are my next projects, and I don't consider a Tikka a Sow's ear. The Tikka has a multitude of issues on upgrading which I am working through now. The Remington 783's have a LOT going for them, and are machined very true, more so that the Savage 10's.
The Remington 783, maybe the very best value on the market today for a foundation for a semi custom in as far as how "True" the action is machined...those with Ears, let them Hear. Upgrades on stocks and triggers choices will be a challenge for both the 783 and the Tikka, unlike the Remington 700 and the Savage.
People tend to get emotional or practical in their choices, but in the end I hope that we can respect another's opinion for where they are in their hobby's development at this stage in their life.
