If you mean Trustile they are beautiful doors much nicer than Masonite, but a lot more expensive, at least the time I used them.

Go with a Masonite solid core door. The disadvantage of solid wood doors (besides expense) is that they have a tendency to warp and/or shrink/expand over time and with changes in temperature/humidity.

TruStile are head and shoulders better than anything Masonite, not just the door but the hinges, door jamb and assembly quality. They are a real, tru stile and rail door as opposed to a hardboard pressed surface door. All depends on your budget. An do not look at just the price of the door, consider the installation costs and the amount of time you will look at the doors and the overall home package.

That $315 is not really "upgrading" anything but the ability to block some sound. Those will never be the equivalent in quality to a door that cost 4x as much. But, is your house worth truly upgrading? You might as well keep what you have, and keep the money in your pocket.

I was told https://residential.masonite.com/products/door/interior/2-panel-roman/YxZ484 this has a solid wood frame and the panels are pressed HDF or MDF. My current doors are terrible, I think the previous owner bought the cheapest door on the market for sale, 5 years later they are all warped. Need to replace and give a nice coat of paint. Le tme look at Trustile as well. I come from India where I am used to polished solid teak wood doors. They never warped though I used them as bathroom doors in a very rainy warm humid place.
