Hi
I have had a range of dumb Turbo’s and had a Tacx Cosmos, it had a color screen and had built Tacx training programs. Power display speed etc.
I now have the Tacx neo which was usable using the Tacx supplied app and plans and workouts which there are a lot off. I do not use the Taxc plans as i subscribed to TR ($99/year seems great value) The thing i like so much about TR plans is it takes most of the Training mistakes away that i used to make. The right level of efforts, recovery days and Recovery weeks.
A smart trainer will be with you through the winter and the plans will give a great variety of workouts. It was not cheap, but bikes are not that cheap either. If you are going for a smart trainer, i would push the boat out and have TR as well.
